FLP3B and FLM3B

Beta Scintillation Probes

Gamma Scintillation Probes/Data

FLP3B utilizes the same 600 cm²

detector used in the BP17. Mounted in

a wheeled assembly to enable effec-

tive alpha floor monitoring. The

FLM3B is the FLP3B combined with a

Delta-5 ratemeter as seen in picture. A

Separate data sheet is available for

the FLM-3 Series.

This is a gamma scintillation probe for

detection of low-energy gamma and x-

rays, optimized for

125

I, housed in a

lightweight aluminum body. This probe

can be matched with Thermo's portable

survey meters, such as the ASP-2, E-

600, RM-25 or Electra/Delta series.
