The occurrence of radioactive pollution can be one of the most emotive subjects that a pollution manager may have to deal with. Releases around a nuclear power station may be examined with more scrutiny than significantly more toxic releases from other sources. Some of this fear is perfectly rational, arising from the fact that there is no safe level of radiation exposure and that radioactive substances may survive in the environment for thousands of years. However, there is also an important sociopolitical context for this reaction, arising from the atmosphere of the Cold War and the reaction to the potential use of nuclear weapons and thus a distrust of any form of nuclear technology.
