DESCRIPTION: For rapid, thorough
monitoring of floors, the T/A model BFM-1 Floor Monitor combines three
thin window GM detectors to form an over-lapping uninterrupted coverage
twenty-four inches wide. A full inch of lead shielding in all directions
but down minimizes any effects of changing general background. The
lead shield may be rotated forty-five degrees to allow the detectors
to ``see'' baseboards. The heavy duty ball bearing casters have
replaceable rubber tires should contamination be a problem. Built-in
loudspeaker and 3-range meter contribute to speed and accuracy of
system. A separate probe is included for checking personnel, etc.
24'' full coverage no dead spots - overlapping detectors.
30 mg/cm² wall detectors. See betas from 0.2 MeV.
halogen quenched for infinite life.
1'' lead shielding all directions except down.
Shield may be rotated 45° to see baseboards.
Separate probe for localizing individual spots or for checking
personnel or surfaces other than floor.
Unit is 35'' wide, has 24'' coverage, weighs 190 lbs.
