Description

A compact search device with a telescopic tube for quick detection and localization of alpha, beta, gamma, and X-ray radiation sources.

The device features an alpha, beta, gamma-sensitive Geiger-Muller counter with a mica window. A big display with luminescent backlight simultaneously indicates units of measurement, measurement errors, threshold level, and real time. Analog indicator of radiation intensity facilitates the localization of radiation sources.

STORA-ABG allows storing up to 1000 measurement results in non-volatile memory, view them on the indicator and transfer the results to a personal computer via Bluetooth in real-time mode.

Purpose of Use

Purpose of Use

  • measurement of ambient dose equivalent rate (DER) of gamma and X-ray radiation (hereinafter – photon-ionizing radiation)

  • measurement of surface beta-particles flux density

  • measurement of surface activity of beta-emitting radionuclides
