A radioactive isotope of phosphorus, 32P, is used in internal radiotherapy to treat patients with cancers and other diseases of the bone marrow. 32P has a half-life of 14.28 days and a atomic mass of 32P is 31.973 u. Via -2 decay, it emits an electron with an energy of 705 KeV and a RBE of 15 .

As part of a treatment program, a patient ingests a radioactive pharmaceutical containing 32P which has an initial activity of 1.4 MBq.

1) How many electrons are emitted over a period of 6.5 days?

2) What is the total amount of energy absorbed by the patients body during this period?

3) If the radiation is absorbed by 124 g of tissue, what is the patient's equivient absorbed dosage?
