P5 A reindeer owner finds a 5-year-old reindeer roast in his freezer. When the steak was placed in the freezer, it had an activity of 1600 Bq/kg from ^137 Cs. The threshold value for selling meat is 155 Bq/kg. ^137 Cs decompositions with- decomposition. a) write the reaction formula for the decay and calculate the activity of the 5-year-old clean tick and determine if the activity is below the limit value. The reindeer owner, who weighs 70 kg, eats 300g of his reindeer roast. as a model, we imagine that he has reindeer meat in him for 24 hours. With each decay, aparticle is sent out. These have an average energy of 0.3 Mev. in approximately 94% of the decompositions, a y-photon with the energy 0.66 MeV is also emitted. We assume that allparticles are absorbed in the body, but the y-photons leave on average one third of their energy to the body. B) What is the absorbed dose for the reindeer owner?
