No not breakfast with LENi. This LENi has a built in pancake tube, as well as external sausage tube. In the tradition of the Ludlum 3-98, and T/A TBM-3 this...
K-40 puts out a nice little Gamma ray at 1460 keV, along with some Betas. A small percentage (.0117%) of all natural Potassium will be the isotope K-40. It is...
Yes sir I felt the same way. But I also thought some of the group may also be interested in the filters. an ordinary disposable OSHA approved face mask is...
