Most get the max radiation which is appx 70 Gys and that is spread over usually 7 weeks, 5 days a week or 35 treatments. So 70 divided by 35 = 2 Gys per day avg. Some RO's accelerate the radiation by doubling up on one day of the week, usually Friday, and by doing so they hope the extra radiation (boost) will have more of an impact and therefore they shorten the weeks by one.
