Radionuclide Identification Devices/Contamination Measurement Radiometers
PM1401K-3 is the smallest and the most lightweight instrument in the world, which is capable to operate simultaneously as an alarming device, search instrument, survey meter, spectrometer and identifier.
The instrument can be used both indoors and outdoors and is intended for everyday and/or emergency use by officers of radiological and isotope laboratories, specialists of different industries, agriculture, transport, medicine, customs and border services, firefighters, military, police and other first responding agencies.
