The tissue-equivalent scintillator used in the Micro Rem and Micro Sievert gives them a nearly flat, rem energy response. This rem response is based on the deep dose equivalent index for 1 cm (0.39”) depth, uniparallel directional beam as calculated on the ICRU standard sphere. These instruments give tissue- equivalent photon response for x-ray and gamma radiation from environmental levels of 0-20 μrem/h (o-0.2 μ Sv/h) full scale up to normal survey levels of 200 mrem/h (2 mSv/h) full scale. Rugged construction and quality components make the Micro Rem and Micro Sievert durable, and they are easy to service. Internal components are laid out on modular circuit boards. Span, HV and calibration pots (one for each range) are clearly marked. The HV check assures you that the high voltage required for proper operation of the detector is supplied. This is important for accurate readings. Two 9-volt batteries power the instrument. You can check their condition with a control switch setting. Applications - Routine low/medium level gamma dose rate surveys - Confirming radiation boundaries - Monitoring items for unrestricted release - X-ray surveys, using the expanded low energy range option Options You can “customize” your instrument with practical options to match the requirements of your survey situation. Options can be combined for maximum versatility. The expanded low energy response option extends the instruments low energy cutoff to 17 keV (vs 40 keV for the standard instruments). The extended detector option mounts the internal detector so that its sensitive area extends out from the front of instrument case bottom. This makes it easier for you to survey certain hard-to-reach locations. Product Specifications Micro Rem / Micro Sievert Tissue equivalent survey meters The Micro Rem and Micro Sievert models are lightweight, portable survey meters for applications where accurate dose rate measurements of low radiation levels are required.

The tissue-equivalent scintillator

used in the Micro Rem and Micro

Sievert gives them a nearly flat, rem

energy response. This rem response

is based on the deep dose

equivalent index for 1 cm (0.39”)

depth, uniparallel directional beam

as calculated on the ICRU standard

sphere.

These instruments give tissue-

equivalent photon response for x-ray

and gamma radiation from

environmental levels of 0-20 μrem/h

(o-0.2 μ Sv/h) full scale up to normal

survey levels of 200 mrem/h

(2 mSv/h) full scale.

Rugged construction and quality

components make the Micro Rem

and Micro Sievert durable, and they

are easy to service. Internal

components are laid out on modular

circuit boards. Span, HV and calibration

pots (one for each range) are clearly

marked.

The HV check assures you that the high

voltage required for proper operation of the

detector is supplied. This is important for

accurate readings.

Two 9-volt batteries power the

instrument. You can check their condition

with a control switch setting.

Complete Flat Energy Response

The rem response and accuracy set the Micro Rem and Micro Sievert apart from conventional "micro R" meters which use Nal(TI)

detectors. Nal(TI) detectors over-respond to low energies and produce erroneously high readings. Also, with with conventional “micro R”

meters the user must to convert μR/h readings to μrem/h to get absorbed dose.

Micro Rem / Micro Sievert Specifications

Power Reactors: Because of its sensitivity and accurate readings, you can use the instrument for setting the boundaries of specific dose rate areas. The over-response of micro R meters often leads to unrealistic boundaries (through buildings, past a fenceline, etc.).

X ray Device Monitoring: A MICRO REM or MICRO SIEVERT, with its expanded low energy response option, meets or exceeds the instrumentation requirements of 21 CFR1 020.10 and 21 CFR1 020.40. You can use oneto survey color TV monitors and all cabinet X-ray systems.

Uranium Processing/Mining Cleanup Operations: The tissue equivalency (rem response) of a MICRO REM or MICRO SIEVERT produces much

more accurate environmental measurements than do micro R meters.Additional Applications: The instrument has many uses for environmental measurement companies, consultants,

geophysical companies, laboratories and accelerators.Radiation Detected: Gamma and x-ray, 40 keV to 1.3 MeVDetector: Internal, tissue equivalent, organic scintillator.Range: Five linear ranges:
