Study of sea life shows exposure to tritium +increase in temp may increase DNA mutation
Rising temperatures could accelerate radiation induced DNA effects in marine mussels
Increased sea temperatures could dramatically enhance and accelerate radiation-induced DNA effects in marine invertebrates, a new study suggests.
Led by Plymouth University, in conjunction with the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the research for the first time explored the impact of rising temperatures coupled with the presence of tritium, an environmentally relevant radionuclide, on marine mussels (Mytilus galloprovincialis).
Studies carried out under laboratory conditions demonstrated that at radiation dose rates considerably below the recommended international guidelines, induced DNA strand breaks appeared earlier at higher temperature compared to lower temperature. At 15ºC, DNA damage was only significantly elevated after seven days in contrast to 25°C where a similar response was observed after three days.
Scientists involved say this suggests an acceleration of radiation-induced DNA damage and potentially compromising defence mechanisms as indicated by changes in…

Hong Kong still testing food imports for Fukushima’s radiation
More than five years ago on Friday, March 11, 2011, the Great East Japan Earthquake with a magnitude of 9.0 set off a large tsunami sending a 50-foot wall of water over three Fukushima Daiichi reactors. Three of the nuclear cores melted down in the next three days.
About 1,600 miles away on the next day, Saturday, March 12, 2011, the Center for Food Safety (CFS) in Hong Kong began stepped up surveillance of fresh foods including milk, vegetables and fruits, imported from Japan for radiation testing.
Eleven days later, on Wednesday, March 23, 2011, CFS discovered three samples imported from Japan with radioactivity levels exceeding those considered to be safe by international Codex Alimentarius Commission.
CFS is a unit of the Food and Environmental Hygiene Department of Hong Kong’s City government, which is part of China. The CFS continues to test those Japanese imports but hasn’t found any additional shipments with unsafe radiation levels.
