- Calculate the mean free path for the two isotopes of hydrogen for a thermal neutron. Use 1.11g/cm3 as the density of heavy waterarrow_forwardTechnetium-99m (99m is mass number 99 but "meta-stable") is used in hospitals for radiation therapies. Unfortunately, the useful form has a half-life of 6 hours which limits the ability to transport it to remote locations. Radio-chemists developed a solution, the "Molybdenum Cow" or moly cow, which is a laboratory apparatus that can be used to make samples of Technicium-99 in hospital radiation labs. Every 1/2 hour or so you can wash a solution through the cow to produce a certain amount of isotope, then you have to wait for the reaction to generate more. Balance the Nuclear equation to determine what particle is emitted when the cow is making Technicium-99 milk. 99 Z Mo → 99m Z TC + A Z Particle (a) Balance the equation and determine what the emitted particle is (replace the red items as needed). A A A El→ El+ Particle Z Z Z Another isotope you deal with every day is potassium-40 which is a beta emitter. Natural potassium on earth has this isotope so biology can deal with it and you…arrow_forwardStrontium-90 is a radioactive byproduct of nuclear reactors (and nuclear weapons) that behaves biologically much like calcium (also in Group II on the periodic table). Consequentially, it can accumulate in the milk of mammals and then into the bone when ingested. This is a particular concern when children ingest milk in significant amounts that has been contaminated by 90Sr. The public first became aware of this potential threat decades ago when the United States was involved in atmospheric atomic bomb testing; one of the major concerns about health impacts of nuclear tests regarded public exposure related to the intake of 90Sr in contaminated milk. By what type of nuclear process (reaction) is it formed from U-235? First, write a reaction showing this, assuming that the reaction was initiated by an energetic neutron colliding with the uranium nucleus and resulted in the formation of a Sr-90 nuclide plus three additional neutrons, plus some other product (see fig). Next, write two…arrow_forward
