As per the revelations of a new report, a team of scientists from Japan, which helps in setting national radiation exposure limits, has been found to have its overseas trips sponsored by the nuclear plant operators of the country for years.

The trips are meant for the International Commission on Radiological Protection's meetings, the report finds. It was in a 600-page parliamentary investigation held into the nuclear power plant disaster last year in Fukushima that has revealed the potential conflict-of-interest in just one sentence.

It was a medical doctor, who pointed out the reference to some source. The doctor was on the investigation panel of a total of 10 persons.

The report says that the scientists have provided with consistent optimistic assessments regarding the radiation health risks. And their main role behind setting policy, which was done after the March 2011 tsunami with nuclear meltdowns, was the difference between families staying or evacuating and schoolchildren playing indoors or outside.

While the International Commission on Radiological Protection (ICRP) believes that no exposure to radiation means no health risks at all, the eight Japanese ICRP members say that low dose exposure is also harmless.

However, the money accepted by the scientists with the aim to cover travel expenses has been accepted by scientist. He said that it had no influence on his science.
