The chart also puts things in terms of Fukushima, where maximum radiation levels have nearly doubled the highest dose limit for US radiation workers in life-saving situations. https://gizmodo.com ...

Scientists uncover surprising immune response that helps tumors grow, revealing new strategies to improve treatment ...

The International Commission on Radiological Protection sets radiation guidelines for human health, recommending dose limits of 20,000 microsieverts per year, averaged over five years (so 100,000 ...

Some types of tumors respond well to radiation therapy, whereas others are refractory to treatment. The molecular underpinnings of these differences are now coming to light ( pages 484–490 ).

Tsai CJ, McBride SM, Riaz N, Lee NY. Reducing the Radiation Therapy Dose Prescription for Elective Treatment Areas in Human Papillomavirus-Associated Oropharyngeal Carcinoma Being Treated With Primary ...

As I noted earlier, radiation levels at Japan's Fukushima power station have reached 400 millisieverts (mSv) per hour. The chart below (posted by @ gakuranman) helps put this figure into perspective.

This study looked at improving the outcome of radiotherapy for non small cell lung cancer. This meant adding extra radiotherapy sessions to an intensive radiotherapy treatment plan called CHART.

This helped to avoid healthy tissue. So it was possible to give a bigger dose of radiation without increasing serious side effects. The main aims of this study were to: see if it was possible to give ...
