APPLICATION: Models HSM-10A, and
HSM-10B Hand and Shoe Monitors are health physics instruments
designed to provide completely automatic detection and measurement
of beta-gamma (plus alpha in case of HSM-10B) contamination
on the palm and back of each hand, the bottom surfaces of both shoes,
and also the hair and clothing. Extremely simple operation allows
the individual worker to perform this check without direct supervision
of the health physicist.
DESCRIPTION: The HSM-10 series
monitors feature large full color LCD display screen that enable the
user to tell - in one look - whether he is contaminated, and where.
Numerical read-outs are provided along the bottom of the monitor panel, showing the
total count on each hand and the combined count for both shoes.
An outstanding feature of the instrument is the
new lower warning levels, which permit alarm settings as low as the
background count.
A separate rate meter circuit is utilized for the
EXTERNAL CLOTHING PROBE, including a speaker for audible check and
a meter for visual check. All the detecting elements and sections
exposed to contamination are designed for easy decontamination. A
roll of kraft paper is mounted in the base for use over the shoe deck
to prevent contaminated material from dropping into the detector chambers.
(In the HSM-10B quarter mil mylar can be substituted
for the kraft paper to allow detection of alphas.)
OPERATION: No skill is required
in the operation of HSM-10 series monitors. The user merely steps
on the shoe deck and inserts hands into the two waist-high probe openings.
The counting process is started and continued by pressure of the fingertips
at the rear of the probe openings, and by the weight of the person
on the shoe deck. As soon as the counting starts, the ``Ready for
Use'' message is replaced by ``Counter in Operation''
.

HAND and SHOE MONITOR
Model # HSM-10A
Model # HSM-10B
NOTE: If at any time during the
counting cycle, the user removes either hand from the hand probe or
steps off the shoe deck, the cycle will automatically stop and the
orange message, ``Check Incomplete - Reset and Repeat''
will light up. This positive warning prevents erroneous readings.
As soon as the preset time has elapsed, the ``Counter
in Operation'' is replaced by either the green ``Check O.K.''
panel or the bold red ``Decontamination Required'' depending upon whether the radioactivity present is above or below
the alarm setting. If decontamination is required, bold red panels
marked ``Left Hand'', ``Right Hand'', or ``Shoes'' will
light up, indicating the location of contamination. The degree of
contamination is indicated on the digital readout. After the check is completed,
the instrument is automatically ready for the next user.
The CLOTHING PROBE, is used to detect contamination on the hair and clothing.
The output of the clothing probe is read visually on it's own count rate
meter and aurally by the speaker. The clothing Probe consists of the extremely sensitive T/A
Model P-15 Pancake Unit. It has a wide face and a thin window for
fast checking of surfaces and high sensitivity.

HAND and SHOE MONITOR
Model # HSM-10A
Model # HSM-10B
SPECIFICATIONS:
- HSM-10B Identical to HSM-10A except that
thin window (1.5 mg/cm2) pancake tubes are used in place
of side window GM tubes. Overall sensitivity is thus increased and
betas below 0.2 MeV may be detected as well as alphas of 4 MeV or
over.
- Detectors: Four T/A type 1190 thin window
pancake GM tubes for each hand and two for each foot. A T/A P-15
probe with type 1190 pancake tube serves as clothing monitor.
- Sensitivity: Less than .005 µC
of beta above 0.2 MeV. Alpha or lower energy betas are also detected
but with less sensitivity. If protective kraft paper or plastic is
used in shoe probes, these become insensitive to alpha and soft beta
radiation.
