1. GENERAL SYSTEM DESCRIPTION
The Model 70 Spectrometric Personal Radiation Detector (SPRD) represents a major
breakthrough in the field of radiation monitoring, offering the user not only the ability to search
for and locate radioactive material, but also to identify the radioactive nuclides present. This
capability in a fully portable hand-held unit that will permit its use in a wide variety of
applications including:
- Hazard identification and risk assessment
- Inspection of incoming and outgoing material for radioactive contamination
- Inspection of radioactive gauges for leaks
- Search of waste sites for radioactive material
- Employee exposure rate and dose monitoring
- Radioactive source monitoring
- Government inspection for material compliance
- Identification of unknown radioactive material
- Regulatory control of radioactive material
- Classification of radioactive material for a wide variety of users
- Detection of illicit trafficking of nuclear materials
- Monitoring of the radiation situation at nuclear facilities
