Alpha Scintillation Probes

HP-380A

This highly mobile, lightweight moni-

tor includes a ruggedized 600 cm²

scintillation probe and a DELTA5

ratemeter. The FLM3 range is ideal for

rapid, sensitive floor monitoring. It

includes background subtract and

alarm settings for extra sensitivity,

and integrate mode for confirmatory

counting in marginal situations. Steel

roller balls suitable for smooth floors

are fitted as standard. The AEO119A

Wheel Kit, for rough surfaces and out-

door use, offers a smooth ride with

castor action and ground clearance

adjustable up to 5 cm (2”).

Alpha and beta efficiencies are

expressed as a percentage of the 2π

flux of a certified reference

source. Gamma efficiency is

measured in a

137

Cs field.

FLP3A utilizes

the same

600 cm²

detector

used in the

AP6 above.

Mounted in a

wheeled assem-

bly to enable effective alpha floor

monitoring. The FLM3A is the FLP3A

combined with a Delta-5 ratemeter as

seen in picture.

Ranges:

0.1–60,000 cps

or 1–1,000,000

These hand

probes are

general pur-

pose survey

and frisking

probes with excellent sensitivity to

alpha with minimum interference

from gamma backgrounds. The probe

design is constructed from lightweight

aluminum which promotes rugged-

ness and ergonomic handling. This

probe can be matched with Thermo's

portable survey meters, such as the

ASP-2, E-600, RM-25 or Electra/Delta

series.
