The Frisker / Digital Radiation Detector – a ß y x
The Radiation Alert® Frisker is a radiation contamination instrument that has been designed to meet the demands of today’s radiation responder. By integrating the latest electronics with a proven and dependable Geiger-Mueller detector, S.E. International has created a rugged, ergonomic tool that addresses a number of radiological applications.
Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective diameter of window is 45 mm (1.77 in.). Side wall is .012 inch thick.
µR/hr – 1 to 50,000
