MS007: PRD / SPRD Family of Advanced Personal Radiation Detectors

The Micasensor MS007 is a family of advanced Personal Radiation Detectors (PRDs) that integrate the latest technologies in sensor materials, AI-based identification algorithms and patented solutions for directional sensitivity. The units are designed to detect, locate, and identify sources of gamma and neutron radiation; accumulate and store gamma-radiation spectra; provide fast identification of basic radionuclides; monitor personnel exposure during operations and alarm upon detection of dangerous radiation levels.

The MS007 stands apart from other PRDs with two key capabilities: true directional sensitivity and full on-board spectroscopy. The built-in directional mode requires no additional input from the wearer — the unit automatically points toward the highest gamma-radiation level, making source location fast and intuitive. All models can also accumulate, display, store, and identify gamma scintillation spectra, enabling rapid isotope identification in the field.

An advanced NORM rejection algorithm ensures sensitivity to critical industrial isotopes is maintained even in high-NORM environments, while automatic threshold adjustment eliminates the need for manual re-calibration when moving between areas with significantly different gamma backgrounds.

The MS007's rugged, shockproof housing and single AA-type battery make it equally suited for mounting on a vehicle deck or wearing on a belt — an indispensable tool for First Responders, Border and Customs services, and fire and police departments.

There are four basic models of the MS007 Personal Radiation Detector:

Directional gamma PRD/SPRD model MS007-01

The only PRD on the market with true directional capability, the MS007-01 can detect the direction to the source of ionizing radiation using inherent sensor sensitivity, without the use of external moderators or complex location procedures. Directional features offer an intuitive search experience, enabling users in shipyards or large customs ports to quickly and precisely identify the location of an alarming radiation source. For luggage or shipping inspections, directional capability ensures a clear picture is reported to management and any threats can be isolated expeditiously. The detector array supporting the directional algorithm uses state-of-the-art isolation techniques, eliminating the need for heavy collimators and making the MS007-01 the most capable and compact PRD/SPRD available today.

Gamma-neutron PRD/SPRD model MS007-02

A dual-mode gamma-neutron PRD/SPRD based on a CLYC crystal with SiPM readout, the MS007-02 offers outstanding sensitivity to both fast and thermal neutrons due to the Cl and Li components of its detector material, with optional capability for fast neutron spectroscopy. The CLYC-based detector also provides superior spectroscopic resolution — typically less than 5% at 662 keV — which makes the identification algorithm running on the MS007-02 faster and more accurate.

Directional gamma PRD/SPRD model with extended dose rate range MS007-03

The extended dose rate range of the MS007-03 is achieved through an additional detector based on a tissue-equivalent plastic scintillator coupled with a silicon photomultiplier. Using patented technology, it enables measurement of gamma and X-ray dose rate and exposure in high gamma-radiation fields of up to 10 Sv/h. At the same time, the MS007-03 retains full directional functionality via its dual CsI gamma detectors, remaining capable of detecting the direction to sources of elevated ionizing radiation.

Gamma-neutron PRD/SPRD model with extended dose rate range MS007-04

The MS007-04 combines the functionality of a dual-mode gamma-neutron PRD/SPRD equipped with a CLYC detector and an extended dose rate measurement range provided by an additional tissue-equivalent plastic scintillator. This makes it an exceptionally versatile instrument, allowing the wearer to perform search functions while simultaneously monitoring exposure and avoiding potential health risks.
