Description
The Frisker Radiation Detector is handheld, lightweight, single handed radiation contamination instrument that has been designed to meet the demands of today’s radiation personnel for leak testing, surface monitoring, sample screening and personnel screening. By integrating the latest electronics with a proven and dependable Geiger-Mueller detector, SE International has created a rugged, ergonomic tool that addresses a number of radiological applications. The Radiation Frisker detects alpha, beta and gamma with an assortment of units of measure, customizable alarm levels and a backlit display.
Each unit includes a rubber boot, lanyard, and batteries.
