|
| Q6
AC2.3 |
Identify the appropriate treatment (therapeutic radionuclide, brachytherapy or x-ray therapy) for the following types of tumour and justify your choice.
· Multiple small tumours · Shallow isolated tumour · Tumour in close proximity to a radiosensitive organ
|
| Q7
AC3.1 |
Explain the possible effects of a range of types of radiation on animal cells. Identify stochastic effects and deterministic effects. Briefly describe methods of monitoring radiation dose and outline how this information can help to alleviate deterministic effects.
|
| Q8
AC3.2 |
Compare and contrast the consequences of radiation damage to somatic cells and to germ line cells.
|
| Q9
AC3.3 |
Estimate the number of decays each day for the following radioisotopes: a) Diagnostic radioisotope with activity 52MBq. b) Therapeutic radioisotope with activity 3800TBq.
|
| Q10
AC3.3 |
Patient X has a 175g tumour and receives 18J of energy as part of their radiotherapy treatment. Calculate the absorbed dose received by the patient.
|
| Q11
AC3.3 |
Patient Y is a worker in the nuclear medical industry. They wear a dosimeter which records their exposure to ionising radiation. During their regular check-up, the dosimeter shows that they have received an absorbed dose of 15mGy from gamma rays and an absorbed dose of 7μGy from alpha particles.
a) Calculate the total equivalent dose received by the patient b) Calculate the effective dose received on the lungs by the patient using the tissue weighting factor WT of 0.12 |
