Radiation Dosimeter DRGB-90

Description

The DRGB-90 radiation dosimeter gives audible and visible measurement of levels of radioactivity (photon rays, hard beta-rays and hard-gamma rays).  It can be used to check the background radiation in a house or workplace and check for contaminated products or food. The dosimeter is intended for use at temperatures from 263 to 313 °K (-10 to 40 °C, 14 to 104 °F).

The radiation dosimeter is used as a portable handheld device.  The case is made of shock-resistant polystyrene.  Its indicators are red and green LEDs and an audible clicker.

Measurements of a level of radiation make on two scales. One (top) scale is for measurement of a level of radiation in microsievert. This scale has three parts. A green part is the presence of radiation levels comparable to the natural background. The yellow part is the presence an allowable level of radiation. A red part is the presence a dangerous zone.

Other (bottom) scale is for measurement of a level of radiation in microroentgen.

Basic Specification:

• This dosimeter contain a Geiger Counter

• Time of measurement is no more than 60 seconds

• The power supply consists of three AA batteries

• One set of batteries will operate the radiation dosimeter continuously for at least 300 hours under natural background radiation conditions

• The radiation dosimeter weighs is 0.25 kg (7 ounces avoirdupois)
