RADEX RD1503 - Radiation Detector/Monitor was developed for detecting radiation in open air and indoors, as well as for basic verification of radiation contamination of materials and objects.

This device was specifically designed for every-day use by people with no knowledge of radiation dosimetry. It is rugged, inexpensive, and has few options to make the use as simple as pressing one button.

RADEX RD1503 contains a low-voltage SBM20-1 type Geiger-Muller counter used in the professional dosimetry equipment.

Not all radiation is the same, so scientists use the ‘sievert’ to measure the health risks of radiation.

SAFE Radiation Dose: 0.09 microsieverts
Exposure: One year living within 50 miles of a nuclear power plant
