- Wireless Handheld Radiation Alert®
( Temporarily Discontinued )
The Abacus is a handheld, digital radiation detection device that enables you to complete your surveys
automatically with your Abacus and a Windows Mobile™, Palm™ Pilot, or Windows™ Computer. Not
only does it offer excellent sensitivity to low levels of alpha, gamma, and x-rays, but the internal peanut
detector automatically performs gamma subtraction from the pancake detector for unprecedented
beta sensitivity. The software can display a variety of units for a wide array of applications, take timed
counts, control the audio, and save your surveys for easy analysis and sharing, all wirelessly right to
your computer! The Abacus also tracks dose, dose rate, and has a red count light, a beeper sound,

and selectable alarm thresholds for quick assessments. The tension-mounted detector head has a
wide range of motion that can be easily adjusted for use in any working environment. Hardware alarms
can be set for quick audio surveys without a computer or handheld device.
