Additional exposure of 10%, 20%, and 30% of the whole body dose
was given to the upper and lower extremities in successive sittings and was thereafter maintained at 30% of the corresponding whole body dose
In 1974, according to the magazine, an employee received a whole body dose
of radiation strong enough to kill 7 out of 10 people.
Proton therapy is highly precise and able to deliver higher doses of radiation to the tumor, lower doses of radiation to healthy tissue and a lower whole body dose
compared to conventional photon therapy.
