Mirion Technology Detectors for X-ray and Gamma Radiation

Mirion Technology Detectors for the detection of gamma radiation are increasingly important, not only as a basic component for satellites used in homeland security and nuclear proliferation monitoring, but also for specialized missions like searches for extraterrestrial radioactive ionizing sources. Especially in the case of CubeSat type spacecrafts, where the available payload is limited, it becomes critical to make sure that these sensors are capable of detecting gamma radiation at the highest possible efficiency, with a minimum of size and weight.

The Mirion Technology  most common type of gamma detector is the proportional counter, a solid-state target that contains scintillating crystals that produce a pulse of light when ionized by gamma radiation. The light intensity is detected by photosensors and converted to a charge signal. This is then read out by front-end electronics and sent to the on-board computer for event processing, which assigns a look-up table priority and event time stamp.

Another popular gamma-ray detector is the sodium iodide (NaI) sensor, which converts ionization to a pulse of light when irradiated. The instrument meter then reads this light signal to determine the energy of the gamma event. The NaI sensors are very efficient at low energies and offer good spectral discrimination, making them ideal for contamination screening. The Flyability Elios 3 drone, equipped with a Mirion sodium iodide gamma detector, recently conducted remote radiation surveys at Idaho’s nuclear waste storage facility and was able to identify hot spots at the site. The results were crucial to allow for detailed planning for the waste removal process.

Mirion Technology Detectors for Nuclear Medicine

Mirion Technology gamma spectrometers and liquid scintillation counters help nuclear power plants identify and quantify radioactive isotopes in process samples. These measurements are used to maintain optimal reactor chemistry, ensure regulatory compliance and detect any issues that could threaten equipment or safety.

Mirion Technology Radiological food screening systems use gamma spectroscopy technology to measure the activity of key nuclides that can contaminate foods: Iodine-131, Cesium-134 and Cesium-137. Our portable system allows samples to be analyzed in a shielded environment and reports the sample activity based on pre-set nuclide specific limits.

The Mirion Technology SAGe well detector combines excellent low energy resolution performance with a large detection volume for small sample sizes. This allows for a high efficiency counting geometry that approaches 4p. SAGe well technology is also used on the New Horizons spacecraft to collect data about Pluto and the solar wind interaction.

In nuclear facilities, sampling and analysis of radioactive materials often takes place in radiochemistry count rooms. Our gamma spectrometers, liquid scintillation counters and other monitoring equipment help determine the presence and concentration of radiation-emitting chemicals in reactor coolant, effluent and other process streams. These analyses help maintain optimal reactor chemistry, ensure regulatory compliance, and quickly detect any leaks or problems.

During decommissioning, site environmental characterization and waste management activities, it is critical to accurately identify alpha-emitting nuclides. Whether in a nuclear facility or off-site environmental counting lab, Mirion Technology provides turnkey alpha/beta counters with integrated signal processing and gamma spectroscopy software. Our LB4200 series systems feature Gas Stat gas conservation that reduces P-10 consumption by up to 50% compared to traditional multi-detector manual counters. A front LED indicator shows counter status and provides start/stop control of the counting operation without the need for additional manual flow valves.

Mirion Technology Detectors for Occupational Dosimetry

Mirion Technology in nuclear power plants and other facilities, radiation detection is critical for ensuring plant safety. Using the latest in detector technology, Mirion Technology monitoring systems network and display data from fixed and mobile radiation measurement devices. These systems help protect the people, environment and the planet from the harmful effects of ionizing radiation, while enabling innovation across diverse end markets.

In radiochemistry count rooms,Mirion technology at nuclear power plants analyze samples of reactor coolant, effluent and other process streams to ensure optimal reactor chemistry, meet regulatory requirements and detect potential issues that could impact plant safety and efficiency. To maximize the effectiveness of this work, highly sensitive instruments such as gamma spectrometers and liquid scintillation counters must be used.

Mirion Technology Personal Radiation Monitoring solutions help prevent radiation exposure in a variety of environments and applications including hospitals, power plants and military/civil defense. These solutions include radiation badges, portable survey meters and handheld field readers. Mirion Technology latest innovations such as the Instadose dosimeter are designed for unmatched efficiency and cost savings. These devices offer on-demand and automatic readings, cumulative dose insights and the ability to update account, device and wearer information online within minutes.

Emergency responders and radiation occupational workers need to be able to trust the accuracy of their dosimetry badges. Mirion Technology AccuRad Personal Radiation Dosimeters feature innovative Variable Background Suppression, allowing operation in varying background environments and alarming only for real threats. These compact and rugged devices are based on Optically Stimulated Luminescence (OSL) technology with 2-element Beryllium Oxide.

Mirion Technology Detectors for Space Applications

Mirion Technology

Mirion Technology detecting radiation in space poses unique challenges, so it’s no surprise that mirion technology is at the heart of some high-profile projects. In fact, the company’s recent participation in the ESA’s JUICE mission to Jupiter’s icy moons serves as just one example of how mirion technology can benefit the space industry.

With traditional dosimeters providing only delayed measurement results, NASA was on the lookout for cutting edge mirion technology that would allow astronauts to monitor their exposure levels in real-time. The result was a custom-designed personal dosimeter using mirion Technology proprietary Instadose+ direct ion storage (DIS) technology to accurately measure and wirelessly transmit the daily dose of ionizing radiation an individual is exposed to.

These dosimeters are used by astronauts and other personnel to help them manage their occupational radiation dose and track their cumulative exposure over time. Mirion Technology dosimetry services are also utilized for environmental and medical monitoring of radioactive contamination in a variety of settings, including nuclear power plants, military sites, oil refineries, hospitals, and medical laboratories.

Flyability’s recent demonstration of Mirion Technology drone radiation survey meter mounted on an Elios 3 drone showcased the equipment’s ability to reliably collect LiDAR and radiation data within a half-century old nuclear waste vault in Idaho. The mission was part of a series of successful trials completed alongside multiple energy companies across the U.S and Europe that helped verify the viability of remote radiation surveys conducted with Elios 3 drones.
