GENERAL DESCRIPTION: Alpha plus Beta Gamma
Floor Monitors, Models ABFM-5, 6, & 7
utilize alpha-beta-gamma sensitive detectors coupled to appropriate
electronics. An electronic sorter accepts and displays alpha counts
only or alphas plus beta-gamma, or beta-gamma only. Windows are protected
by a frame and grid which may be easily removed for decontamination
purposes. The very large face detectors achieve, as far as we know,
the fastest most sensitive floor monitoring system currently available.
Figure 1: ABFM-Series
SPECIFICATIONS: Three additions
to Technical Associates Floor Monitor Group.
12 large window thin form GM detectors,
29 sq. inches coverage in 24 inch swath. Window 1.5-2 mg/cm2.
Sees alpha plus all common betas except H-3. Adjustable height above
floor. The ABFM-5 sees all
alpha beta and gamma together. It does not sort.
4 PM tubes collect information
from 144 sq. inches of plastic phosphor protected by thin light-tight
easily replaceable window plus grille. Window is less than 1 mg/cm2.
Sees alphas plus all common betas except H-3. Switch selectable:
alpha only or beta-gamma
only or all. Digital and analog
readout. Adjustable height above floor. Output for recorder.
144 sq. inches thin window gas
flow dual detector. Window is less than 1 mg/cm2. Sees alphas
and all common betas except H-3. Also sees X-rays
(eg H3 bremstrahlung) and gammas down to 5 KeV but with
less efficiency. Switch selectable for alpha or
beta-gamma or all.
Also has pulse height analyzer. Analog plus digital response. Adjustable
height above floor. Output for recorder. Includes gas supply (P-10).
