health risks[edit]

According to x-rays produce 35 double strand breaks (DSB) in the DNA per cell per gray. This means e.g. if someone who would have a brain CT with 100mGy exposure, then 3.5 additional DSB/cell would be added. According to that article, 20% of skin cells exposed to 200mGy suffer 7 DSB per cell, and can't function any more, and die. I read that nerve cells are supposed to be more resistant to radiation, but didn't find any research supporting that. So perhaps, if someone does a brain CT, he is saying goodbye to 20% of his brain. According to 25% of DSB are not repaired well.

Adverse effects[edit]

Shouldn't we mention in the article that a protein found in Tardigrades may help human DNA to withstand radiation ? See here KVDP (talk) 14:00, 28 June 2017 (UTC)

Contradictory text in "Early research"[edit]

"Eugen Goldstein proved that they came ... and named them ...." refers to the antecedent X-rays from the immediately preceding text, but then names cathode rays instead. I can't correct the contradiction myself without the resources to know just what he proved and what he named.--William Mestman (talk) 09:44, 20 July 2017 (UTC)
