c) A patient has a CT scan of their abdomen with an absorbed dose of 25.0 mGy. The scan ends near the top of their pelvis. Assume that 15% of their bone is scanned, 20% of their skin, 90% of their colon, 25% of their bladder and 10% of their lungs but none of their liver, stomach and gonads. A further 20% of tissue characterised as 'remainder of the body' is also exposed during the scan. The tissue weighting factors for various organs is listed in the table below: Tissue Tissue weighting Tissue Tissue weighting factor factor skin 0.01 oesophagus 0.04 bone marrow 0.12 bladder 0.04 bone surface 0.01 breast 0.12 brain 0.01 gonads 0.08 lung 0.12 thyroid 0.04 liver 0.04 salivary glands 0.01 stomach 0.12 remainder of body 0.12 colon 0.12 What is the overall effective dose received by the patient from the CT scan?
