Radioactivity detector RADEX RD1008 is designed for detecting of ionizing radiation and estimating of the ambient dose equivalent values, the ambient equivalent dose rate of photon (gamma- and roentgen-) ionizing radiation and the beta-particles flux density.
This device is used to estimate the radiation level on the ground and in the premises, and to evaluate the radioactivity contamination of products by gamma- and beta-radiation sources.
RADEX RD1008 has the following features:
- simultaneous evaluation of ambient gamma-radiation dose-rate and beta-particles flux density;
- evaluation of the accumulated dose for two users;
- continuous evaluation with result correction;
- quick automatic reset in case of sudden change in dose rate or radiation flux density;
- indication of the received background values on the display;
- indication of excess over the background values of the measured dose-rate value or the particles-flux density value on the display;
- time of measurement decreases as the ambient dose-rate increases;
- increased number of measurements in the cycle, resulting in higher data precision;
- change of alarm threshold for gamma- and beta-radiation;
- estimation of gamma-radiation dose with the registration of measurement time;
- for the alarm, audio or vibration signal can be used;
- calibration coefficient may be modified by the user.

TECHNICAL SPECIFICATIONS
The device estimates the radiation situation according to the value of ambient equivalent dose rate of gamma-radiation N*(10) dose (hereinafter – EDR) taking into account X-radiation, according to the value of beta-radiation flux density and the ambient equivalent-dose of gamma-radiation (hereinafter – the dose).

(1) time of measurement depends on the dose rate. Increase of the number of measurement cycles results in increase of the data precision.
(2) time of continuous work of the device with the battery 3100 Ah capacity, when the natural background doesn't exceed 0,30 mSv/h and with the factory settings.
