Quarta-Rad RD1008 - The first handheld radiation detector that detects and displays radiation results for Beta- and Gamma- as two separate values.
It was designed for detecting ionizing radiation and estimating the ambient dose-equivalent values, as well as the ambient equivalent dose-rate of photon (gamma- and roentgen-) ionizing radiation and the beta-particles flux density.
Summary of the Working Specifications
The device uses two table sensors for detecting radiation (Beta-2 and Beta-2M). While the cost of the device increased significantly due to the use of these sensors, they do allow this detector to detect and display radiation results for Beta- and Gamma- as two separate values.
This the first time that a small, hand-held device can accurately measure the presence of Beta- and Gamma- values in products.
It is astonishing considering that this device weighs only 175 g / 6.2 oz (compared to the typical 10 kg / 25 lbs and above for an equivalent).
- simultaneous and separate evaluation of Gamma- and Beta-particles
- ability to accumulate dose for two users (acts as a dosimeter)
- continuous evaluation with self-test and result correction
- automatic re-test/re-set in case of sudden change in dose-rate or radiation flux-density
- ability to show Background on display and excess of Background
- short measurement cycle
- measurement cycle decreases as the ambient radiation increases
- ability to track measurement cycles
- ability to change alarm thresholds for Beta- and Gamma-radiation
- ability to choose audio or vibration alarm
- calibration coefficient may be modified by the user
