Specialized - Radiation Counter ·GeigerMullerCounter
Permanent-sensitivity Geiger-Müller counter for alpha and beta radiation. Its windowed detector construction provides pulse-counting response to charged-particle radiation for laboratory and survey measurements.
Small end-window neon/halogen Geiger counter for medical-isotope work, with low background count and low-voltage operation.
