During the testing process for some pharmaceuticals, the drug is \"tagged\" with a radioactive material. This way researchers can determine if the pharmaceutical is going to other parts of the body than the intended target and what effect it has on the non-target areas. By adding this radioactive tag to the pharmaceutical, researchers can pinpoint all parts of the body and the concentration that accumulates in non-target areas. One possible such tag is technetium-99, 99Tc, which has a half-life of...

1 GBq of a 99mTc tagged colloid is injected into a patient to visualize the liver, the mass of the liver is 2.0 kg. around 4% of the injected activity is deposited in the liver. The biological half life of 99mTc in the liver is 3 days whereas its radiological half-life is 6 hours. Assuming all of the 99mTc decays by 141 KeV photon emission. What is the instantaneous absorbed dose-rate to liver in mGy/hr
