Here is the family history as I know it.

Mom died of lymphatic cancer 2003

I have a rare form of immune system disorder (ADEM) that nearly killed me, but
left me disabled, in 2003

Brother has numerous problems with IBS and gastric problems, though he was
carried there by my mother.

Father died in 1955 by self inflicted gunshot.

I spoke with a surviving member of the family that went out with us that day and
she said the place was "off limits" then.   No one was allowed there, but my dad
and his friend brought us out there to see it.   We walked all the way to the
remnants of the tower.   That green glass was all over in large shards crunching
under foot.   She said, to me, we were "stupid 20 year olds, not realizing how
dangerous that site was"   But she has had no adverse effects.

Steve

Trinity Site has preserved a section of Trinitite, covered by a low shed, and visible thru a window during tours.

Mostly all gone now.

" I wonder how hot that site was back in 1955?

Steve."

Steve, out of morbid curiosity, how has that family group fared health wise over the years? There may have been a reason the area was off limits back then??

This is sort of a continuation of Message #30685.  My son's HS Rocket Club has a
project to launch a science payload a mile high.  They plan to send an array of
10, LND719 G/M tubes up and log data during the parachute descent.  This array
should gather data 50 times faster than a 6993 tube.  The idea is to determine
if there is region of minimum radiation a thousand feet up or so.  I don't  know
if it will work, or even if it has a chance, but it will be fun.

We experimented with a few of the ideas this group discussed:

1) Use a MP3 recorder to log data and CDVcounter to read it.
2) Use a Stamp2 microcontroller to log data
3) Use an inertial switch to begin logging data

#1 worked but was difficult.  Volume (both recording and playback) settings and
CDVcounter threshold settings had to be just right to get consistent results.

#2 required me to learn a little about microcontrollers, which I did.  Miguel V.
on GCE taught me how to condition G/M pulses for the digital world and I will
teach the payload team.  This looks like it is going to work beautifully.  This
was a great suggestion.

#3 will probably be dropped in favor of a $16.00 accelerometer telling the
Stamp2  (or Picaxe) when to start logging counts.  It is all in the code.  This
time, I am going to make the boys figure out how to do this.

Their club put up a website (below) this week, but all it has is their proposal
to NASA.  If you click "Proposal" and go to page 25 you will see the CCFL HV
power supply we built to experiment with and on page 26 is a graph of
MP3/CDVcounter data.  This data shows the same test MP3 file run through
CDVcounter twice.  It was not identical but the basic trend was there.

Mike L.

Hi Mike!
 
  Glad to help. Yep, the HV didode is indeed a piece of work! IIRC, the 400 uF cap is just an integrating cap for the meter (moved recently, CDV books not found yet).
  Thus, if you go higher, it will dampen the meter response, but that's it.
  Good Luck!

Thanks Doug & Tom.
Taken mine apart and it's definitely a 6A, which seems to be in favor by many for various reasons in the reading I've done on the web.
The construction of the high voltage diode stack(CR5) is an interesting story in itself.
I plan to replace it with a couple 1N4007 diodes.
Does it seem to matter if the 400 uF elect cap(C2) is replaced by a 6.3v 470 uF cap?
Thanks for the high voltage probe tip - I've got one at work I can borrow.

Miguel, we like the Canary Islands a lot. Some are very dry, due to the winds
blowing off the Sahara. Back when we were doing volcano explorations, Lanzarote
was one of our destinations. You can cook meat on the ground, and if you stick
paper in some crevasses, it will burst into flames on it's own!

Division for Sales of Uranium Enrichment Services, Enriched Uranium and Isotopes

TENEX (Techsnabexport) is an exclusive sales representative of ROSATOM on the global market of uranium enrichment services, enriched uranium and isotopes. The company was founded in 1963 as a foreign trade agent of Soviet nuclear industry. The 100% of its shares are owned by Atomenergoprom.

The company became widely known in 1993, after Russian-American government-to-government HEU Agreement (“the Megatons and Megawatts” agreement on converting highly-enriched uranium (HEU) extracted from Soviet nuclear missiles into low-enriched uranium (LEU) to be used in the fresh fuel for the US nuclear power plants) was concluded. Since 1993, every tenth bulb used in the USA has been lit by the fuel produced from Russian weapons plutonium. In the 15 years that the agreement was under implementation, more than 350 t of plutonium have been downblended of the total 500 t to be converted by 2013 when the HEU Agreement is due to expire. This amount is equivalent to 14,000 nuclear warheads delivering 10,200 t of low-enriched uranium for fabricating nuclear fuel for American NPPs. The federal budget of Russia received more than $7.6 bln in the last 15 years owing to this activity. 

TENEX is steadily expanding its operation on the market of low-enriched uranium and uranium products. Thus, it holds 30% of the market in France which is the EU leader in nuclear generation, and 40% on the African market (South Africa). Owing to TENEX, Russian uranium products are available on the Latin American market (supplies to Brazil and Mexico), are well-known in Japan and South Korea where the company has opened its offices. The company gears up to signing direct contracts to supply uranium products to the US utilities on the end of the HEU Agreement.

The annual export turnover of Techsnabexport exceeds $2.5 bln.; the company accounts for the three thirds of the nuclear technology export in Russia.

Went up to the Grand Canyon with Dave, my uranium-cigar smoking buddy, to test
my two PRI 117 scintillators.   Gamma only reading, one has a plastic crystal,
the other a restored crystal by Allyn Goshy.

It is amazing how sensitive they are.   At least 50 times as much as a CDV-700.
I read background readings at El Tovar that were 2 to 3 times normal background
of ~.02 mRHR  We went to the Orphan Mine, which is a super-fund site, and the
road leading there was covered over with a tarp, and sandbagged down.   I got
readings there that were 4 to 5 times normal background.

Then along the tracks, near the El Tovar where the mine once sent ore, the
readings were the same significantly higher than background.   Even some of the
bushes were radioactive!  Registering to peg the most sensitive scale at .25
mR/HR above background.

Then on the way out I went to a rock shop and did some exploring.   I discovered
a pile of obsidian that was quite a bit above background, about 3x.   The whole
pile, but not one piece alone.

Then I put it to the real test to see if I could spot some radioactive wood.  
Amazing, from several feet on the most sensitive scale the needle was pegged
when I went over a piece buried in the pile.    Not strongly radioactive either,
and such pieces barely register on the CDV-700.   But they are nevertheless have
significant and measurable amounts of uranium.

Got several pieces of radioactive petrified wood, and two chunks of dinosaur
bone that show activity.

On the CDV-700 these pieces register only 300 to 1000 CPM close to the probe
with beta shield open.   And barely measurable with beta shield closed.   But
with both the PRI 117 scintillators, one with a plastic scintillator and the
other with NaI, the samples I found can be detected from several feet.

These two old scintillators are great, and some nice things will be found with
these.

The plastic scintillator has a slower response on the meter than the one with
NaI crystal.  But that aside both responded very close in the overall readings
that I got.    And it is odd that some samples registered exactly the same,
while with other samples from the same area the plastic scintillator was off by
about 20%.   (Must be due to a different energy spectrum from the samples.)  
But the scintillator with the plastic crystal is many times more sensitive than
a standard CDV-700.   I would estimate at least 50 times more so, and close to
the NaI which is a bit more sensitive.

Plastic scintillator material  is a viable option for units where their original
crystals are beyond repair.

I will be trying some other plastic scintillator designs to see if I can arrive
at the best shape to further enhance the response.


Steve.

I have a great DVD, "Hollywood's top Secret Film Studio", that is documentary about Lookout Mountain Air Force Station.  This was a Defence Dept. production company in L.A. that was used to film all the surface testing in the 40s and 50s.  There is a scene that shows these rockets lined up on a beach (Eniwetok?) prior to the Wahoo Umbrella test.  They look to be 8 feet long or so to me.

Incidentally, the video starts with a Film Institute party honoring these film makers.  The room was full of nuke veterans in their 70's.  One old fellow, a Mr. Woods, says he was often sent home for having "too much radiation" for the year.  He claims he filmed 80% of the shots, starting with Operation Crossroads in 1946.  Mr. Woods did look well tanned, but otherwise OK.
Mike,
 
Where did you get that DVD? I'd love to find a copy. An interesting thing about "Lookout Mountain" is that there were several peaks in the Hollywood Hills that seemed to acquire that name. I think the studio may have been part of the installation at Mount Lee, the peak on which the HOLLYWOOD sign is mounted. This was originally owned by Don Lee, W6XAO, who set up the first experimental TV broadcast station there. Later, it was a research facility, apparently pretty fancy at one time, they even had a pool.
 
The "other" Lookout Mountain was a WWII Radar Site at the top of Sunset Plaza Drive near Beverly Hills. I have pictures of this site as it existed in 1956 when our High School Radio Club, K6CXI conducted Field Day operations there. There was one structure left, a concrete building with windows PAINTED on the side, so it would look like an ordinary house viewed from the air. There were two poles probably used to support a wire antenna, and a few other leftovers. Here's a shot of the peak from the approach road:
 
 
And from the other side:
 
 
Sometime in the late 60's the mountain top was leveled, and expensive homes were built up there. The only thing left was a telephone company repeater to the East.
 
If you want more pictures of this site I can send them to your personal E-mail address. I didn't want to clutter the forum, but thought other users might find these interesting as well.

Mike,
 
Just to clarify, I was born and raised in Los Angeles, so I am quite familiar with the area. The photo is of yet another of the sites that was called "Lookout Mountain." The major portion of this site was below ground. I explored portions of the site many, many years ago. I do not believe it is currently still in existence. It is NOT the Mt. Lee site, as there were no homes around the Mt. Lee site. That site is still there, at least as of 2005, the last time I visited the area. It is still some kind of research facility, now gated. Almost ALL the other installations, the radar sites, the Nike missile sites, etc. are all long gone. There are some remains of the Nike site behind the Huges Experimental Aircraft field on National Blvd. near Playa Del Rey. Everything else has been obliterated by urban sprawl.
 
Hold off on sending the DVD, I will attempt to order it from the source you sent. If I am unable to do so I will let you know. Thanks a bunch.

The movie is apparently now called "The Atomic Filmmakers".
It was directed by Peter Kuran, the guy who did "Trinity and Beyond".

Hi Mike!
 
  Congrats on your purchase and welcome aboard!
  The Vic 6A is fairly robust. In fact, other than a Lionel, I would next prefer the 6/6A, as the Vic 6B has a Unobtanium coupling transformer that goes pffft! with all too much regularity.
  What I would do is check and clean battery contacts, switches, and heat shrink sleeve the battery clips.
  The clips were designed for paper clad batteries, and will eventually cut through the thinly plastic insulated batteries and cause a meltdown. It's not a matter of "if" but "when". You have been warned!
  Beyond that, the HV diodes do go bad often. You can replace it with a string of 2 or 3 1N4007's in series.
  Transistors will fail, check the junctions, all of them!  They can be replaced by 2N404, 2N404-A, and other PNP Germaniums...
  Listen for the popwer supply oscillator: You should hear the mosquito sound of the PS transistor working. If you hear it, you probably have B+.
  If you measure the HV, use a DMM or VTVM with a 990-1000 MegOhm "HV" isolation probe.
  The supply is high voltage at fractions of a microamp, so any leakage at all or any loading such as from a directly connected voltmeter, will pull the B+ down and give you wrong readings.
  The HV blocking cap does break down once in a while, slagging the metering transistor.
  This is for starters. I highly recommend Doug's advice of replacing the electrolytics.
  Let us know how you make out!
 
-Tom

Greeting to the group.
I'm looking for a link to a troubleshooting guide for the Victoreen CDV-700 No. 6A detector.

I'm a electronics tech by trade and just bought an "as is" unit off of Ebay, intending to restore it to full functionality.

Mike,
 
Where did you get that DVD? I'd love to find a copy. An interesting thing about "Lookout Mountain" is that there were several peaks in the Hollywood Hills that seemed to acquire that name. I think the studio may have been part of the installation at Mount Lee, the peak on which the HOLLYWOOD sign is mounted. This was originally owned by Don Lee, W6XAO, who set up the first experimental TV broadcast station there. Later, it was a research facility, apparently pretty fancy at one time, they even had a pool.
 
The "other" Lookout Mountain was a WWII Radar Site at the top of Sunset Plaza Drive near Beverly Hills. I have pictures of this site as it existed in 1956 when our High School Radio Club, K6CXI conducted Field Day operations there. There was one structure left, a concrete building with windows PAINTED on the side, so it would look like an ordinary house viewed from the air. There were two poles probably used to support a wire antenna, and a few other leftovers. Here's a shot of the peak from the approach road:
 
 
And from the other side:
 
 
Sometime in the late 60's the mountain top was leveled, and expensive homes were built up there. The only thing left was a telephone company repeater to the East.

We went to Holloman's air show a couple weeks back. They had a Predator parked
on the tarmac, along with all the rest. The F-22 Raptor wasn't parked where we
could walk up to it, though it taxied right by us. All the readings at Holloman
were normal background.

Doug,

I have a great DVD, "Hollywood's top Secret Film Studio", that is documentary
about Lookout Mountain Air Force Station.  This was a Defence Dept. production
company in L.A. that was used to film all the surface testing in the 40s and
50s.  There is a scene that shows these rockets lined up on a beach (Eniwetok?)
prior to the Wahoo Umbrella test.  They look to be 8 feet long or so to me.

Incidentally, the video starts with a Film Institute party honoring these film
makers.  The room was full of nuke veterans in their 70's.  One old fellow, a
Mr. Woods, says he was often sent home for having "too much radiation" for the
year.  He claims he filmed 80% of the shots, starting with Operation Crossroads
in 1946.  Mr. Woods did look well tanned, but otherwise OK.

Regards,

Mike Loughlin

Hmm,

We have 8 different jobs on different parts of WSMR right now.  I need to take mine with me and see. 

A couple of jobs are up at Stallion near Trinity Site.  Also have jobs at Holloman AFB, too.  Saw some Predators flying low last week over there, along with the F-4s and F-22s.  And of course, the old relic German Tornadoes the Luftwaffe stationed at HAFB still fly.  Those damn antiques are loder than the F-22s!

The background here in Las Cruces for me is usually around 10uR/hr with my PM1703.  Had it deer hunting SW of Deming this weekend, and it got up to as high as 24uR/hr climbing in the hills.  Not too unusual.  I get the same thing up in the Organ Mtns, from the granite, I would guess.  I almost took mine with me on the Bataan Memorial Death March on WSMR back in March, but I decided not to carry it the 27miles...

Since we were going to Las Cruces Saturday, I decided to take along the PM1703M. It's about 65 miles from here in Alamogordo to Cruces, and I-70 goes right through White Sands Missile Test range. I put the detector on my dashboard where I could see it.
Background here is 7-9 uR/hr, which it was most of the drive. Almost as soon as we entered the test area, the readings started to creep up.
It hit 28 uR/hr for a short distance, but hovered around 16-18 most of the time through the range. Upon leaving the area, and cresting over the Organ mountains, looking down on Cruces, it went back to normal.
I believe Trinity was at least 50 miles north of here, and a search revealed that site is 2x background. If I'm hitting 4x background on the x-way, I wonder what hot spots are out there, and what caused them?
Through the range on the way back it went to 20.

Point taken. I don't think I was suggesting his activities specifically led to his Cancer, just pointing out a fact. I managed to expose myself to lots of X-rays during experimentation as a teenager, but I have made it to 70, had three healthy kids, and so far no signs of any ill effects.
 
However, the native population in the Marshall Islands did indeed suffer many ill effects as a result of the testing there, especially the children. Lawsuits and compensations are still being negotiated today. They probably did not have the protection that most of the scientists had.

Half the people around you will die of cancer.  The other

in cars or from invisible agents called germs.

Unusual cancers are noteworthy.  Otherwise, you're just

Some famous athlete just declared leukemia.  Bet he's never

I'm not saying there might be a causal link sometimes --military folks are

Mike,
 
I'm not aware of a specific trouble shooting guide, but there is a publication that suggests some modifications to increase the reliability of those units. I think it's in the FILES section somewhere, but if you don't find it I could E-mail you a copy.
 
They are fairly simple units, but suffer from some common problems such as shorting of the battery holder clips and transistor failure. I think the modifications correct the latter problem. Probably lots of people here can give you advise. I just finished rebuilding one and it wasn't much of a chore. I recommend replacing the HV diode and the 400uF integrating capacitor. They have been marginal or bad in all the ones I have rebuilt.
 
Regards,

Yes those are rocket trails, pout there to monitor certain parameters in the
air, later were replaced with advanced sensors. This is a fact, verified by a
long time worker ( and tour guide) at the Nevada Test site. He had personally
observed some 80+ air detonations all over the world!

I had a very good friend who was in charge of the cleanup of fallout on the
target ships, at Bikini. They went out immediately after the detonation with
brooms, swept the debris off the decks, and gathered up the goats and pigs that
were tied up there, for checkout.

He always bragged that he had never been sick in all those intervening years.

One day he quite coming to lunch. He had gotten some super rare cancer and soon
died.

Justin Case,
 
    Have you seen the documentary "The Atomic Cafe?" There is a film of a test in Nevada where troops come up out of trenches after a nuclear device detonation and proceed to walk right into the fallout cloud. Do you know if these people were monitored for later effects?
 
    Also, in a lot of the blast pictures, I see vertical trails next to the "stem" of the mushroom. I believe these are rocket trails, the rockets being possibly sent up seconds before the blast to monitor some parameter. I've never had anyone confirm this, however. You can see them clearly in the classic B&W shot of the Trinity test.

Trinity Site has preserved a section of Trinitite, covered by a low shed, and
visible thru a window during tours.

Mostly all gone now.

Steve, out of morbid curiosity, how has that family group fared health wise over
the years? There may have been a reason the area was off limits back then??

Some years ago I visited the public section of White Sands. At the time, the hottest spot I found was the front wall of the visitor's building. :-) Out on White Sands, backgrounds were quite low.
