ITS RDX-1 Low Range Radiation Monitor & Detector | Geiger Muller Tube detects Gamma, Beta, and X-ray Radiation | Range: 0-100µSv/hr and 0-10mR/hr | not affected by EMP | Instant Reading

This low cost portable geiger counter instantly measures levels of harmful beta, gamma, and X-ray radiations on its compressed dual scale meter. It features a range of 0-100uSv/Hr and 0-10 mR/Hr (logarithmic). The DX-1 nstantly indicate levels of Beta, Gamma, and X-Ray radiation by audible clicks from an internal speaker and by the compressed-scale meter. At higher radiation levels the speaker beeps, indicating elevated radiation levels. The beeping will begin above 10 mR/hr, intervals between beeps decreasing in relation to field strength, becoming a continuous alerting tone above 20 mR/hr. The DX-2 is useful for measuring higher levels (compacting several ranges into one scale) and features the ability to be recalibrated via a backside adjustment screw. A single pushbutton activates the DX-1 and DX-2 only when needed, conserving battery power. An LED indicator alerts you of battery condition upon each use. Applications for the units are many and may include checking for environmental contamination, industrial, clinical, field, school classroom, home use, or wherever radioactive materials are present. Perfect for rock and mineral enthusiasts for its simplicity and convenience in identifying naturally radioactive rocks and ores, or for workers handling radioactive minerals, metals, and isotopes who are concerned about unknowingly bringing home contamination on their clothes and shoes. The device measures 6" x 3" x 1.37" and operates on 1- 9V battery (included).
