Detectors, Environmental, Ionizing Radiation, Low-Level

Definition : Ionizing radiation detectors designed for automated discovery and/or ascertainment of the presence of very low (typically up to 500 or 1,000 miliroentgen/ hour) ionizing radiation levels that are not a short-term hazard to humans. These detectors may use one or several different sensing devices, including Geiger tubes and/or other ionizing chambers. They usually include visual and/or sound indicators to show that ionizing radiation is present (e.g., flashing lights and/or beeper sounds for each radiation event) but do not include displays showing the radiation level. Low-level detectors of ionizing radiation are used mainly in areas where a radiation leakage has or may have occurred, to check low-level contamination in food and/or water, and to evaluate the results of decontamination procedures. Many low-level detectors become saturated when exposed to high radiation levels (e.g., more than one roentgen/hour), making them useless to detect dangerous (or even lethal) ionizing radiation levels that are present in some nuclear emergencies. Low-level ionizing radiation environmental detectors are used by healthcare personnel, rescuers, and firefighters in radioactive or potentially radioactive contaminated areas.

Company Type: Parent

Historically, Rexon Components Inc. was the second spin-off (1983) from the Harshaw Chemical Co. which pioneered the development of inorganic scintillators in this country and the free-world. Rexon's creation originated due to a change in Harshaw's management and philosophy. The founder, Dr. M. R. Farukhi had served at Harshaw as Group Leader for Measurements (R/D), Director of Production Engineering, and finally as Manager of Nuclear Products and Systems. Several of Dr. Farukhi's publications now serve as references for the properties of scintillators. Rexon's managers are veterans in the Nuclear Radiation Detector industry with primary experience at Harshaw. These managers are well aware of all the nuances in the fabrication technology. Rexon Components is at the forefront of Homeland Security. Our products are helping security worldwide. Rexon's Products and Services cover the entire gamut of products offered by the SGIC Companies of France which include the now-defunct Bicron, Harshaw Q/S, and Crismatec.
