Large amounts of 65zn are produced in copper exposed to accelerator beams. while machining contaminated copper, a physicist ingests 45.0 µci of 65zn. each 65zn decay emits an average γ-ray energy of 0.550 mev, 40.0% of which is absorbed in the scientist's 60.0 kg body. what dose in msv is caused by this in one day?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
