1.a. A 14-gram ovarian tumor is treated using a sodium phosphate solution in which the phosphorus atoms are the radioative phosphorus-32 isotope with a half-life of 14.3 days and which decays via beta emision (RBE=1) with an energy of 1.71 MeV. Half of the sodium phosphate is absorbed by the tumor and deposits 9.0 J energy into it. The other half of the solution is absorbed throughout the patient's tissues, also depositing 9.0 J of energy into the 50.0 kg of body tissues. i.

58. . Radiation treatment of prostate cancer. In many cases, BIO prostate cancer is treated by implanting 60 to 100 small seeds of radioactive material into the tumor. The energy released from the decays kills the tumor. One isotope that is used (there are others) is palladium (10°Pd), with a half-life of 17 days. If a typical grain contains 0.250 g of 10°Pd, (a) what is its initial activity rate in Bq, and (b) what is the rate 68 days later?
Disintegration. NUCLEAR PHYSICS. Explain what it's being used. It has been found that a sample of uranium oxide (U308), freshly prepared from an ore of uranium, emits 20.5 a particles per mg per second. If we have A238 = 4.8 × 10¬185-1, is it possible to have a 1mg sample?
3. A 100kg sample of Neptunium 234 (Np234) was accidentally released due to the gross negligence of Jerf, the worst nuclear engineer ever. A. Jerf plans to act as though nothing happened until 95% of the sample has decayed into other elements. How long will they have to keep waffling about pretending to do experiments? (hint: Wikipedia knows the half-life of (Np234)) B. After two weeks, Jarrison, Jerf's supervisor, notices Jerf has had a minor decrease in productivity and decides to confront Jerf. Realizing their jig is up, Jerf decides to eat as much as they can before Jarrison notices. Assuming they eat 5 kgs of Np 234, how much is left for Jarrison to find? C. Following this incident, Jarrison, along with the EPA, makes a graph detailing the amount of Np 234 in Jerf's lab. Draw this graph and label all important events. Do not include the amount of Np234 that Jerf ingested, as a serendipitous genetic immunity to radiation Jerf inherited is the only reason they did not succumb to…
