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
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
■ Detects and displays level of BETA particle dose rate from 0.01 microgray per hour to 5
■ 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.
