Fig 43-14 gives an exploded view of a radiation film badge ) Management may have film badges and dosimeters serviced, films developed, and exposure records maintained as a part of plant operations Depending upon the work load, it may prove more economical and provide better control and protection for a plant to purchase this service Several ex cellent film badge service companies are available In either case, all monitoring records should be retained by management Legal counsel will advise on what steps should be taken to ensure that such records will be admissible m court cases. It is not wise to allow a person to work alone with large quantities of radioactive materials or on the off-shift since adequate help will not be available to cope with spills, lasses of material, or injuries Involv ing radioactivity Adequate roles covering special clothing, bathing facilities, and protective equipment are required Wearing contaminated cloth ing outside the control limits must be pro hibited. If there is danger of ingestion of radioactive material, then smoking and eat ing should be limited to "clean" areas 42-35
