This report is one of a series in which the results of Public Health England’s environmental radioactivity surveillance programme are presented.
In general, the radionuclides detected result from nuclear weapons tested in the atmosphere in the 1950s and 1960s and from the nuclear reactor accident at Chernobyl in the Ukraine in 1986, although the programme is able to detect any other sources of significant contamination. The results indicate that concentrations of artificial radionuclides in the general environment remain at the low levels observed in recent years.
There is no evidence of any very low levels remaining in the environment from the Fukushima Dai-ichi accident in 2011.
Samples of airborne dust have been collected in the vicinity of the Sellafield nuclear fuel reprocessing plant in west Cumbria. The results are consistent with those published by the site operator and other government agencies.
