Radioactivity spills

After a radioactive spill or other contamination of persons or environment, immediately notify the laboratory instructor so that he/she can inform the... 

Since this is an in-process test, special caution must be given to radiation protection. The test equipment should be placed within a closed and shielded unit and a system should be in place to collect any radioactive spill from the test. 

Measurement of man-made (artificial) radionuclides, including identification and determination of amounts (e.g., fission products, fallout, radioactive spills, and leakage from waste disposal sites or other facilities). 

The Chernobyl reactor had serious design problems. Unlike U.S. reactors, the Chernobyl reactor had no confinement shell surrounding it to contain radioactive spills. Another problem was the design of the cooling system. The fuel core had a graphite moderator with water cooling in... 

The production of plutonium was a prime justification for building NRU and took precedence over other uses. Some would be used for reactor experiments in Canada, but it was expected that most would be exported to the United States for atomic bombs. Isotope production came next on the list of priorities, so CPD would have fair access to the reactor. NRU started up on November 3, 1957. After a shakedown period, irradiations began. In May 1958, a fuel rod broke as it was being withdrawn from the reactor, causing a radioactive spill that delayed cobalt-60 production to late 1959. 

When a major radioactive spill on the floor occurs (without injury to personnel), the operator must immediately ... 

Most laboratories have access to a health physicist or radiation protection officer at the installation who can advise and assist in the event of a radioactive spill. This individual must always be notified immediately if a spill occurs. There are several steps that should be... 

For workers at hazard from radioactive spill it is cleariy of great advantage to have an adequate blood level of penicillamine, or the preferable chelating agent, before entering the area of risk.
