NDM Gauges

One-day training course for Radiation Protection Supervisors.

09:30	Introduction to Radiation Protection A summary of the industrial use of radioactive sources, public perception of the risk and the objectives of the course.
09:45	lonising Radiations Radioisotopes; decay and half-life; sealed sources; units of activity; radiation and contamination; properties of the radiations - by demonstration; 137Cs and 241Am/Be in nuclear density/moisture gauges.
10:30	Radiation Dose Dose quantities and units; background exposures; benchmarks of dose; dose limits for workers; ALARP; dose-rates expected from sources in NDM gauges. Coffee
11:15	Video : 'All Around Us - Radiation'
11:45	Management of Radiation Work with NDM Gauges Protection of the environment by the RSA93; protection of persons by the IRR99; - Controlled Areas; appointment of RPS & RPA; classified workers; 'authorised workers'; constant supervision; Systems of Work; dose assessment; leakage tests; notifications and record keeping; content of the Local Rules; transport requirements. Lunch
13:30	Monitoring Radiation dose-rate instruments and contamination monitors; calibrations and function checks; operational monitoring requirements; emergency monitoring; interpretation of readings; action levels.
14:15	Health Effects and Principles of Protection Health effects of low dose irradiation; avoidance of high dose effects; protection by time, distance and shielding.
15:00	Risk Assessment and Contingency Plans The most reasonably foreseeable accidents; procedures to be adopted in the event of gauge failure, fire in store or accidents involving the radioactive sources. Tea
15:50	Nuclear Density Gauge Accident Evaluation Groups given time to consider an accident involving an NDM gauge and the response required from the RPS.
16:20	Course Questionnaire and discussion
