High Dose DosimetersThe Mirion High Dose Dosimeter reliably measures exposure for non-personnel working environments such as radiation therapy, research applications, equipment calibrations, or 
sterilization applications. The High Dose is the perfect measurement device in environments where radiation dose levels exist between 2 and 50,000 rads. A reliable LiF TLD chip offers excellent response, and is energy and dose independent for most levels up to 1,000 rads. Above that level, Mirion employs optical density filters, which reduce the excessive amount of light which TLDs emit, so the PM tube does not become saturated and assessment accuracy is assured.
In facilities where employees work with neutron generators or Linear Accelerator Cyclotrons, the CR39 provides accurate exposure determinations. The CR39 may be used separately for neutron detection, or in conjunction with other dosimeters such as the Mirion Film and TLD whole body dosimeters. Exposure to neutrons cannot be detected by film and requires a specific calibration for TLD dosimeters.
The Mirion CR39 neutron dosimeter is energy independent and a practical and convenient way to accurately monitor exposure to intermediate and fast neutron radiation.
Environmental TLD 110
Mirion offers an environmental dosimeter that is well suited to monitor low-level gamma radiation and to withstand most intense environmental situations. This dosimeter is designed for outdoor applications and may be used to measure radiation for site characterization, at site boundaries for regulatory compliance, and to monitor public exposure. The Mirion Environmental Thermoluminescent dosimeter, encased in a holder that protects against moisture, provides quick attachment to fences, gates, trees, or other objects in the environment.
REMtrack TM Wallet CardThe Mirion REMtrackTM dosimeter is a personal radiation dosimeter. These wallet cards are extensively used by first responders, homeland security personnel, counter-terrorism operations, law enforcement and other personnel who encounter radiation emergency situations. 
REMtrack TM can also be used by members of the general public who want to be aware of the radiation environment to which they may be exposed.
REMtrack TM consists of natural lithium fluoride chips positioned between high quality paper and polyethylene laminated material. Its unique bar-code identification system displays an individual’s name and card number; including card issue and expiration dates, and offers an accurate chain-of-custody through the analysis process. This whole body dosimeter comes in a convenient credit card size and is intended to monitor radiation doses for up to a year.
