CR39 Neutron Dosimeter
|
Complete Monitoring for Intermediate and Fast
Neutron Detection
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 GDS Film and TLD whole body
dosimeters. Exposure to neutrons cannot be detected by film and requires a
specific calibration for TLD dosimeters. The GDS CR39 neutron dosimeter is
energy independent and a practical and convenient way to accurately monitor
exposure to intermediate and fast neutron radiation.
Applications
Occupational radiation workers who work at a linear
accelerator, cyclotron facility, or are exposed to fast neutrons 5 MeV.
(Energies greater than 10 MeV must have a site-specific calibration
performed).
Features
 | Establishes a permanent record of exposure.
|
| Can be combined with a number of different dosimeters,
or used alone. |
| Energy independent. |
| Responds to intermediate and fast neutrons.
|
| Accurate image analysis counting system. |
| Energy spectrum analysis is capable if used in
conjunction with a GDS Thermoluminescent dosimeter. |
| Wear periods from 1 week to 1 year. |
| Computer-controlled automatic counting system provides
objective, error-free dose assessments. |
