This professional Radiation detector is a precise instrument to measure alpha, beta and gamma radioactivity. The Radiation detector has a wide measuring range and can be used for diverse measurements types as for sporadic measurements in situ, long-lasting measurements or for controls.
The Radiation detector provides with a certified measurement of the environmental radiation as well as the radiation which is artificially increased up to 500 times over the limit value.
This Radiation detector has diverse applications. This Geiger meter has been usually used in nuclear power stations. Everyday it is most commonly used in the control of imported goods, as well as to measure the food which has been previously irradiated. This Radiation detector can be also used to measure natural radioactive radiation as the one which appears near the sea and it fulfils all the requirements when controlling building materials.
Radiation values can be recorded in the Radiation detector memory or they can be transferred to a computer to be valued by means of a device included in the delivery (software and RS 232 data cable).
Radiation Detector GS 3
Measuring principle / Radiation detector Geiger-Müller counting tube, auto shut-off, stainless steel case with halogen filler
- measurement length = 38.1 mm
- measurement diameter = 9.1 mm
- window = 1.5 ... 2.5 mg/m²
Radiation types - Alpha radiation from 4 MeV
- Beta radiation from 0.2 MeV
- Gamma radiation from 0.02 MeV
Selection of the diaphragm - Alpha + Beta + Gamma (without diaphragm)
Beta + Gamma ( (approx 0.1 mm) alpha is totally protected)
- Gamma (display Al (approx 3 mm) alpha and beta radiation are totally protected approx. 2 MeV, it attenuates Gamma under 7 %)
Gamma Sensibility 95.0 impulses / min for radiation Co60 Null quota < 10 impulses / min
with protection 3 mm Al y 50 mm Pb
Measurement ranges 0.01 µSv / h - 1000 µSv / h Measurement of the impulses 1 ... 99 s, 1 ... 99 min, 1 ... 99 h,
mean value 24 h in µSv / h
