2. for an identified substance calculate the LET if average energy required to produce an ion pair is about 22.5 ev and there are 3800 ion pairs per cm
3. if a 3 cm thickness of material transmits 42% of an incoming beam of photons calculate the hvl of the beam
4. what is the effective half-life of a substance if it's physical half life is 0.75 days and biological half life is 5 days
5. an iodine 123 capsule is given to a patient early in the morning at 10 a.m. it is calibrated to contain 85 microcuries at noon find the dosage of 123I administer to the patient at 10 a.m. if the half life of 13 hours in microcuries
