Even Low-Level Radioactivity Is Damaging, Scientists Conclude

9. WRONG!!!

caraher,

LNT was NOT validated. In fact, we know that LNT can't be correct since there is a DNA radiation damage repair mechanism.

Health Physicists know that LNT is wrong; but use it for developing regulations since it over-predicts the effects and is thus conservative. That's fine for making regulations.

However, if you are actually exposed to radiation, a Health Physicist will NOT use LNT to estimate your risks.

Recent results from Lawrence Berkeley National Lab published in the prestigious Proceedings of the National Academy of Sciences suggest that low level radiation exposure is LESS harmful than previously estimated:

“Our data show that at lower doses of ionizing radiation, DNA repair mechanisms work much better than at higher doses,” says Mina Bissell, a world-renowned breast cancer researcher with Berkeley Lab’s Life Sciences Division. “This non-linear DNA damage response casts doubt on the general assumption that any amount of ionizing radiation is harmful and additive.”
