GM Probes

For easy monitoring of surfaces, cloth-

ing and equipment, PGM’s 15.5 cm²

radiation window, of thickness only 1.4

to 2 mg.cm², provides high efficiency

and is protected by a fine mesh BeCu

screen. All versions operate at 900 V.

GM pancake probe with rugged probe

housing, responds to alpha, beta and

gamma radiations. The ECPGM’s

detachable energy compensation

shield lets you convert the response

from count rate to gamma dose rate.

See graph above. The ECPGM is

matched to the Surveyor 2000E. The

PGM can be matched with the

Surveyor, ASP-2, E-600, RM-25 or

Electra/Delta Series. See also HP-360

and HP-210.

A side window probe that incorpo-

rates a sliding housing. SWGM

detects high-energy beta and gamma

with the side window exposed but

gamma only when the slide is closed

to shield the GM tube. This probe can

be matched with Thermo's portable

survey meters, such as the Surveyor,

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

series.

Type SL is a cylin-

drical glass walled

GM tube in a

rugged housing

for detecting medi-

um and high-ener-

gy beta emitters,

with an active length of 120 mm

(4.72”). The SLR version incorporates

a moveable beta shield. Thermo's

portable survey meters, such as the

ASP-2, E-600, RM-25, Surveyor or
