A person with lymphoma cancer receives a dose of 35 gray in the form of gamma radiation during a course of radiotherapy. Most of the dose is absorbed in 18 grams of cancerous lymphatic tissue.  i.  How much energy is absorbed by the cancerous tissue.?  ii.  If this treatment consist of five 15 -minute sessions per week over the course of 5 weeks and just one percent of the gamma photons in the gamma ray beam are absorbed, what is the power of the gamma ray beam?  iii.  If the gamma ray beam consists of 0.5% of the photons emitted by the gamma source, each of which has energy of 0.03Mev, what is the activity in Curie of the gamma ray source?
