Mylar/Poly Film Dispenser Option (PCM2 OPT8)
Myiar/Poly Film
Dispenser Option
Parts List
This option incorporates a thin mylar or polypropylene film supply and take-up
roll system into the PCM-2's base to provide the user with a simple and easily
accessable method of protecting the unit's foot detector from the frequent
contamination caused by users shoes. The system has been designed to manually
advance the thin film sheet over the foot detector and onto a blank take-up roll
where the contaminated particles are trapped between film layers, to later be
discarded along with the used protective film sheet. The remaining blank supply
roll core is then used as the take-up roll when a new supply roll is installed. The
film is manually advanced by inserting a hexagonal shaft driver into the take-up
roll shaft center hex screw, thru a small hole in the front of the PCM-2's base,
and rotating the take-up roll 2 to 3 complete clockwise turns. A storage clip for
the hex driver is located inside the PCM-2's side door.
As noted, two choices of protective film media are available with this option. The
polypropylene material is 0.0005 in. thick. The mylar material is 0.00016 in.
thick and is, therefore, better suited for alpha radiation monitoring. Both
materials are furnished on cardboard cores in 200 ft. lengths
This option offers the user a greater degree of foot detector maintenance than do
the standard cardboard-framed 0.0005 thick film protectors in that contaminated
particulates released from users shoes are contained in the take-up roll when a
fresh width of film is drawn over the detector. The thinner mylar material
available with this option also decreases the impact to the overall sensitivity of the
foot detector.
