TB 9-6665-285-15
1. Purpose.
This technical bulletin (TB) delineates responsibilities, instructions, and
guidance for effective calibration and repair of RADIAC instrumentation.
2. Applicability.
This TB is
applicable to US Army
Activities, Army National
Guard, and
US Army Reserves, using or providing calibration and repair service for RADIAC
instrumentation. It will serve as a minimum guideline for the US Army Primary Standards
Laboratory.
3. Definition of Terms. RADIAC
instruments are portable test, measurement, and
diagnostic equipment (TMDE), such as Geiger counters or ionization chambers, used to
detect ionizing radiation and to measure dose or dose rates. RADIAC instruments may
detect or measure alpha, beta, gamma, X-ray, or neutron radiation and may be expressed in
various units of measure. All RADIAC instruments are related to health and safety (H/S)
and are categorized as follows:
a. RADIAC Instruments - ACTIVE. Instruments used full or part time in day-to-day
ionizing radiation safety operations on Army installations or by Army personnel (civilian
and military) for making quantitative measurements of radioactive contamination and/or
determining radiation levels. Instrumentation classified in this category is utilized
anywhere personnel handle, use, maintain, store, transport, dispose of, or are exposed to
materials or equipment that produce any type of ionizing radiation (i.e., alpha, beta,
gamma/X-ray, or neutron radiation).
b. RADIAC Instruments - RADIOGRAPHIC. These are ACTIVE instruments that
are used to measure radiation from sealed source gamma radiation producing by-product
material used in radiography operations on Army installations or by Army personnel
(civilian or military). Although the technical calibration requirements for these items are
the same as those for like ACTIVE devices, there are additional requirements specified in
Title 10, Code of Federal Regulations, Part 34.24, Safety Requirements for Radiographic
Operations, which separate the support of the instrumentation in this category from similar
equipment classified as ACTIVE.
used by Army hospitals, clinics, and other medical units to comply with requirements set
forth in Title 10, Code of Federal Regulations, Part 35.51, Medical Use of By-product
Material - Calibration and Check of Survey Instruments. These requirements include
additional calibration documentation and the measurement support of accompanying
dedicated check sources. Technical procedures followed in the calibration of these devices
will be generally the same as those used in the support of like make/model number ACTIVE
items.
measure and determine radiation levels, to identify and isolate radioactive contaminated
areas, and maintained in standby status for dedicated use in the event of a nuclear accident
or incident or radiological dispersal device. This category includes devices utilized by the
Nuclear Emergency Team (NET), the Radiological Advisory Medical Team (RAMT),
Explosive Ordnance Disposal (EOD) units, Civil Support Teams (CST), and other groups
tasked with the responsibility to respond to these situations. Calibration requirements will
