DESCRIPTION: The Alpha Floor Monitor
AFM-2 is similar to the BFM-1 above in concept, but substitutes alpha
scintillation detectors for the GM tubes. The detection system covers
144 square inches at one time providing extreme sensitivity. Since
response to betas and gammas is zero, single alphas may be detected
via the loudspeaker without having to attempt to sort from background.
SPECIFICATIONS:
Covers a 6'' x 24'' area - 144 square inches total
face.
0.9 mg/cm² window allows detection of
alphas from all common nuclides.
High efficiency assured by carefully designed light
pipe configuration and optimization of phosphor thickness and distribution.
