PGR Scintillation Radiameter
 |
Geological Survey Mining Radiation pollution Mapping Radioactive Sources and Solutions Cecking Health Purposes |
 |
|
The PGR Scintillation Radiameter is designed for high sensitive and accurate radiation measurements in wide range of gamma energies with a basic possibility of spectral analysis |
GENERAL DESCRIPTION
|
The PGR scintillation portable radiameter allows sensitive and reliable measurement of total gamma ray activity in field . The 2" x 2" NaItI scintillation unit provides the high accuracy and detection efficiency of the measurement. The PGR is destinated especially for geology , mining , environmental monitoring , industrial and health purposes . The microprocessor controlling unit makes easy interactive operating possible . Three measuring parameters can be continuosly set : the energy threshold , integration time and alarm threshold The measured value can be shown in cps , nGy/h , pA/kg , µR/h . The preset alarm threshold overflow is indicated on display and by acoustic signal . The measured value can be put into the digital memory by pressing the button and data can be transferred to the user’s PC by standard RS232C channel . The PGR meter is designed for measurement in difficult conditions / high umidity , rain . The display backlight allows the measuring in mines or in twilight . The built-in NiCd techargeable cells provide a long and cheap operation time of PGR in field . |
