Whole body dosimeters
Dosimeter overview
The InLight Nova dosimeter uses Optically Stimulated Luminescence (OSL) technology to monitor exposure to X-ray, beta and gamma radiation.
Each InLight Nova dosimeter is shipped fully assembled with the:
- user's name
- serial number
- group number
- wearing location
- wearing period start and end date
Client suitability
Whole body dosimeters can be used in a wide range of occupational environments, including:
- mining
- research
- education
- health care
- industrial workers
- emergency response providers

Whole Body Dosimeters (InLight Nova) - Technical Specifications
Extremity dosimeters
Ring Dosimeter
Dosimeter overview
The ring dosimeter uses thermoluminescence (TLD) technology to monitor exposure to X-ray, beta and gamma radiation.
The ring dosimeter is made by enclosing a thermoluminescent chip underneath the ring cap, which is ultrasonically welded to the ring base. Each ring has an identification label pasted on top. All ring dosimeters are labelled with the:
- Ring serial number
- Wearing period start date
- Wearing location (left or right hand)
Inlight Nova Extremity Dosimeter
The InLight Nova extremity dosimeter uses Optically Stimulated Luminescence (OSL) technology to monitor exposure to X-ray, beta and gamma radiation. The dosimeter is fastened to the wrist or ankle using a Velcro®strap. The wrist and ankle dosimeters are labelled with the:
- user's name
- serial number
- group number
- wearing location
- wearing period start and end date
Client suitability
Ring, wrist and ankle dosimeters can be used by individuals whose extremities are at risk of radiation exposure, such as:
- researchers using radioactive materials
- individuals who use X-ray diffraction machines
- individuals who work with radiopharmaceuticals
- individuals who may be required to hold patients during X-rays, for example in veterinary medicine

Neutron dosimeters
Dosimeter overview
Neutron dosimeters use solid state nuclear track detector technology (CR-39) to monitor exposure to neutron radiation. The dosimeter is packaged in a vinyl pouch specifically designed for neutron detection.
Clients who use the neutron dosimeter may also monitor a broad spectrum of ionizing radiation by using a Whole Body Dosimeter (InLight Nova).
Client suitability
Neutron dosimeters can be used by individuals who may be exposed to neutron radiation, such as:
- oil well loggers
- geotechnical staff

Neutron Dosimeter - Technical Specifications
Electronic personal dosimeters
Dosimeter overview
The Electronic Personal Dosimeter, or the EPD® as it is more commonly called, detects and monitors exposure to X-ray, beta and gamma radiation in real time.
Radiation that is detected by the EPD is processed to give a real time readout to the user via a liquid crystal display (LCD) for deep dose, skin dose and dose rates.
Client suitability
EPDs can be used by individuals who need real-time personal monitoring for dose management purposes such as:
- oil well loggers
- high-risk workers
- pregnant workers
- industrial radiographers
- nuclear medicine technologists
- emergency response providers
- workers in the field of food and materials irradiation
