The MBD-2 dosimeter is a real-time, self-indicating device that requires no user intervention for operation. The MBD-2 dosimeter is based upon Mirion Technologies’ patented Direct Ion Storage (DIS) technology. Direct Ion Storage technology is a method for detecting ionizing radiation through use of an ion chamber detector combined with a simplified method for computing dose from a voltage value from the detector.

The MBD-2 device measures and records dose for gamma, neutron, and beta (shallow). It is ergonomic, and designed to be worn comfortably on the wrist (watch-type), or clipped to a garment (badge-type). The MBD-2 dosimeter is lightweight, dark grey or black in color and low profile in size. Its edges are rounded to accommodate clothing and gear. The device closely resembles a wristwatch and therefore is natural to observe when reading the display.
