‘There is a growing body of evidence that radiation in excess of what the government says are the minimum amounts we should be exposed to are actually good for you and reduce cases of cancer,’ she told Fox News TV host Bill O’Reilly.

Coulter pointed to articles in the New York Times and The Times of London to back up her argument.

‘So we should all be heading for the nuclear reactor leaking and kind of sunbathing,’ joked O’Reilly.

Coulter was speaking after writing a column on her website titled, ‘A Glowing Report on Radiation.’

She quotes a string of doctors to back her argument and writes: ‘With the terrible earthquake and resulting tsunami that have devastated Japan, the only good news is that anyone exposed to excess radiation from the nuclear power plants is now probably much less likely to get cancer.

‘This only seems counter-intuitive because of media hysteria for the past 20 years trying to convince Americans that radiation at any dose is bad.

'There is, however, burgeoning evidence that excess radiation operates as a sort of cancer vaccine.

‘Every day Americans pop multivitamins containing trace amount of zinc, magnesium, selenium, copper, manganese, chromium, molybdenum, nickel, boron - all poisons.

‘They get flu shots. They'll drink copious amounts of coffee to ingest a poison: caffeine. (Back in the '70s, Professor Cohen offered to eat as much plutonium as Ralph Nader would eat caffeine - an offer Nader never accepted.)

‘But in the case of radiation, the media have Americans convinced that the minutest amount is always deadly.’

More than 150,000 people have been evacuated from the danger zone around the damaged Japanese reactor and the U.S. has advised citizens to evacuate from a 50-mile radius of the site.

'Radiation is good for you,' says Ann Coulter as she weighs in on Japan's nuclear crisis
