The readings of these four TLD chips is combined into an overall calculation of neutron dose. In the case of neutron dosimetry, it refers to the measurement of neutrons that are moderated and reflected from the body. Most neutron dosimetry uses this principal of reflection. With four independent detection elements, the badge can measure dose from beta, gamma, x-ray, or neutron radiation over a wide range of energies. The badge may be used for monitoring personnel in medical, industrial, and other nuclear applications.
Beta calibration is geometry dependent.
The badge detects fast neutrons by the albedo effect. Accurate dose assessment requires the use of a source-specific calibration factor. The standard calibration factor is based on an Am-Be neutron source. Calibration factors for other neutron sources, e.g. Cf-252, can be used if requested by a customer. The minimum reportable dose is 10 millirem for gamma radiation and x-rays.
