c. PP-1578/PD Series Charger.
The PP-1578/PD Series Charger is the standard RADIACcharger that is used to place a charge on the
dosimeter. It generates an electrical charge by friction and therefore requires no batteries.
d. IM-174/PD Series RADIACmeter.
This RADIACmeter is used for area monitoring and survey. It is a high-range dose rate meter;
GAMMA radiation readings are indicated in units from 0 to 500 cGy(cGy) /hr. It is normally issued on
the basis of one per platoon-size unit.
e. AN/PDR-27 RADIAC Set.
The AN/PDR-27 RADIAC Set is the Army's primary personnel monitoring instrument and is used to
monitor low level radiation contamination on personnel, supplies, and equipment. It is issued on the
basis of one per divisional company-size combat and combat support unit and as required for medical,
maintenance, and chemical units, and for water supply points. The AN/VDR-2 RADIAC Set will
replace the AN/PDR-27 RADIAC Set.
f. The AN/VDR-2 RADIAC Set.
The AN/VDR-2 has been recently fielded and will replace both the IM-174 Series RADIACmeter and
the AN/PDR-27 Series RADIAC Set. It measures both high and low level GAMMA radiation and
detects BETA radiation. The AN/VDR-2 works on the principal of continuous electrical collection of
ions. The probe of this instrument contains two GM Tubes which use the same detection method as the
AN/PDR-27. It is lightweight, easy to use, battery operated, and self-testing during operation or on
demand by the operator.
The capabilities of the AN/VDR-2 include:
■ Detects, measures, and displays level of GAMMA cGy rate from 0.01 microgray per hour to
100 Gy/hr.
■ Detects and displays level of BETA particle dose rate from 0.01 microgray per hour to 5
cGy/hr.
■ Measures, stores, and displays accumulated dose from 0.01 microgray to 9.99 Gy.
■ Flashes display to indicate reduced-accuracy condition when measuring dose rates from 10
Gy/hr and above.
