The Model 3014 is an ergonomic, lightweight instrument which can be used for radiation
survey purposes. The Model 3014 includes an internal detector for tracking user exposure
rate or dose. The Model 3014 features the ability to measure radiation in count rate, exposure
rate/dose, activity rate, integrated exposure/dose, time-averaged rates, and scaler counts.
The DETECTOR button is used to select between displaying the internal or external detector.
The instrument features a large backlit LCD (liquid crystal display), an audio warning, and
easy, intuitive use. The unit body is made of lightweight but durable plastic. It is intended
for outdoor use and can resist splashing water. The foam grip provides a comfortable, er-
gonomic grip but may be removed for ease of decontamination.
Four modes of operation are available for the Model 3014 – RATE, MAX, COUNT, and DOSE.
RATE mode operation will display the current count, exposure, or activity rate.
MAX mode is used to capture the highest count, activity, or exposure rate detected – useful
for finding a peak rate, or frisking when the display is not visible. Two sets of units (primary
and secondary) for RATE and MAX modes can be chosen from among cps, cpm, Bq, Bq/cm²,
dpm, R/h, or Sv/h. The user can switch between these two units by simply pressing the
UNITS button.
COUNT mode allows the user to perform a count for a predetermined time. Depending on
the count units chosen, the result can be a scaler count (in counts or disintegrations), a time-
averaged rate (cpm, dpm, Bq, Bq/cm², cps), a time-averaged exposure or dose (R/h, Sv/h),
or an integrated exposure or dose (R or Sv).
DOSE mode allows the user to view a real time integrated dose (R or Sv) with the possibility
of continually monitoring the integrated dose during other modes of operation.
The primary keypad includes four push buttons: ON/AUD to toggle instrument power and
adjust the click audio level, UNITS to change between available units, DETECTOR to change
between available detectors, and MODE to switch between available modes.
The standard handle includes a LOG button that allows the instrument to log up to 1000 data
points when activated with the optional Lumic Datalogging Kit.
