From the web page, "In addition to alpha, beta, and gamma particles, the new
"Improved Radiation Meter" encountered lot of success."

I wonder what jumble of words was intended to mean.

You may have to shield from external electronic noise. Also, many black plastics are not opaque through the range of the photodiode. Near IR gets through and...
