palmRAD 907 Nuclear Radiation Meter
The palmRAD 907 is an easy-to-use, portable radiation meter
designed to accurately detect and measure levels of
radioactivity for a multitude of health and safety applications.
Lightweight and compact in design, the palmRAD 907 is
capable of detecting and measuring alpha, beta, gamma and
x-ray radiation using a 2-inch pancake GM detector with high
sensitivity to beta and alpha sources.
Applications
Compliance and Inspection
Emergency Response
Quality Control
HAZMAT
Features
Alarm Threshold
Acquisition Timer
Loud Audible Chirp
palmGRAPH Software
The palmRAD 907 is an economical radiation detection
solution for non-technical personnel in government, law
enforcement or the private sector. The instrument offers the
highest sensitivity to radiation making it an excellent tool for various
applications including industrial, medical or emergency response. A slide
switch on the front panel turns the unit on or off and also allows toggling
between audible and silent chirp modes. Another slide switch allows the
user to reset total counts, or display the radiation activity in mR/hr, CPM,
CPS, or mSv/hr.
The optional stainless steel Wipe Test Plate slides easily onto the 907
positioning the depression and wipe directly in front of the GM tube at a
fixed distance of 1 centimeter. The Wipe Test Plate is removable for
general surveying or decontamination. It can also be used for protecting
the GM tube from damage and the instrument from being contaminated
while the 907 is not in use.
The Total/Timer feature takes timed readings for periods from one
minute to 24 hours for precise measurement of low-level contamination.
Our safety first calibration feature can also eliminate radiation
exposure to the calibration technician. The instrument s user-adjustable
alarms alert audibly and visually when radiation is present and when
preset exposure limits are exceeded. The dose rate or cumulative dose is
shown digitally on the instrument s LCD display. The handheld unit
comes with a protective pouch which secures to a user s belt for
convenience in operation or transportation. The palmRAD 907 meets CE
certification requirements for Europe.
The back panel of the
palmRAD 907 (shown above)
features the 2-inch pancake
GM detector.

Software Package Included
palmGRAPH is a Windows-compatible software
package designed to record and graph radiation measured
by the palmRAD 907 over time. When run in
conjunction with an operating palmRAD 907, the
software will notify the user when user-adjustable alert
levels are exceeded by actual radiation counts. This
software utility also allows the user to measure, record
and display radiation readings over any period of time.
View current palmRAD readings with palmGRAPH, or
display and print graphs showing changes in radiation
levels over time. palmGRAPH software is also useful for
demonstrating gross count measurement theory in a
classroom or training setting.
