There are still widespread bans or restrictions on collecting or hunting mushrooms, berries, and game in many areas where high concentrations of caesium-137 are still found.

Significant levels of radioactive caesium-137, strontium-90 and plutonium isotopes still pollute the ground.

Nisa has already confirmed that caesium-137 and iodine-131 have been released into the atmosphere.

Nuclear scare grows with an orange flash and a violent blast 2011

Robert Peter Gale, a US medical researcher who was brought in by Soviet authorities after the Chernobyl disaster, said recent higher readings of radioactive iodine-131 and caesium-137 should be of greater concern than reports earlier this week of tiny quantities of plutonium found in soil samples.

If nothing else, this should worry smokers: the radiation dose from radium and polonium found naturally in tobacco can be a thousand times more than that from the caesium-137 taken up by the leaves from the Chernobyl nuclear accident.

The fallout from the accident in the early hours of 26 April 1986 crossed over Europe, and deposited the radioactive isotope caesium-137 in mainly upland areas of Wales, Scotland and England.

It said there may be a slight increase in radioactivity in the nearby environment due to re-suspension of caesium-137, "but it would be very much lower than the natural radioactivity."
