A person with lymphoma receives a dose of 35 gray in the form of gammaradiation during a course of radiotherapy. Most of this dose is absorbed in 18grams of cancerous lymphatic tissue.i.How much energy is absorbed by the cancerous tissue?If this treatment consists of five 15-minute sessions per week over thecourse of 5 weeks and just one percent of the gamma photons in thegamma ray beam are absorbed, what is the power of the gamma raybeam?ii.iii.If the gamma ray beam consists of just 0.5 percent of the photonsemitted by the gamma source, each of which has an energy of 0.03MeV, what is the activity, in Curies, of the gamma ray source?

An uncontrolled cell division of abnormal cells or tissue lead to the development of cancer. They…

a) Hemoglobin accounts for 95% of the protein in red blood cells. If you Google the number of hemoglobin molecules in a RBC, most sources state 250-270 million hemoglobin molecules. If hemoglobin has a molecular weight of 67,000 Da, what is the concentration of hemoglobin in RBCs? Show your work and show your units. Use dimensional analysis to have your final answer in moles per liter. B) The hemoglobin molecule is nearly spherical with a diameter of 55 Angstroms. You can look at the 3D structure of human hemoglobin on the RCSB PDB website. Calculate the volume of a hemoglobin molecule, and can the number of hemoglobin molecules quoted in Question a actually fit into one red blood cell?
