Question 1Question A: Define the term RadiopharmaceuticalQuestion B: Describe the production of two different radioisotopes for medical imaging purposesQuestion C: State and explain the key biological and radiological properties of radioisotopes used in medical imaging by comparing the two isotopes that you described in question B Question 2Question A : Describe the process of process of producing a gamma camera image including the preparation of the patient and how the gamma camera works. You will need to include a fully labelled diagram of the gamma camera and refer to it in your answerQuestion B : Give an example of a typical imaging process for a particular condition and state what radioisotope would be used.Question 3Explain the advantages in the use of radiopharmaceuticals for treatment as opposed to irradiation using external sources of radiation.Question 4Describe the effects of alpha, beta and gamma radiation on living cells.Question 5Distinguish between the effects that radiation can have on an adult and those which can result as a consequence of a foetus being exposed to a significant dose of radiation.Question 6Question A: calculate the absorbed dose of radiation for tissue that suffers a mean energy absorbed of 420 joules in a quantity of tissue that has a mass of 60 grams. (No word account)Question B: Calculate the exposure of a section of bone in a case where the absorbed dose is 260 J/kg using a value of "f" value for bone of 160. (No word account) Question C: What is the effective dose for an external source in a case where the absorbed dose is 760 J/Kg and the radiation is in the form of beta particles assuming a RBE value of 1.8 ( No word account)
