Hand Probes
A. GENERAL DESCRIPTION
The HP-270 is an excellent general purpose G-M probe
with energy compensation and a beta shield, making it
the choice for most health physics applications. The
energy compensation permits reliable exposure rate
measurement from background to 3000 mR/h.
The HP-290 is a higher range G-M probe with energy
compensation, providing reliable exposure rate mea-
surement from 0.1 mR/h to 40 R/h.
