- (I) Why the physicochemical changes in liquid water caused by radiation is the key to understanding the biological effects of radiation? Please give a short, one-sentence explanation. (II) Name the three key stages of the physicochemical changes produced in liquid water due to radiation. (III) Briefly describe the three key stages. A one- or two-sentence explanation for each of the three key stages would be sufficient.arrow_forwardPhosphorus-32, a radioisotope used in leukemia therapy, has a half-life of about 14 days.

- At the beginning of an experiment, a scientist has 268 grams of radioactive goo. After 180 minutes, her sample has decayed to 4.1875 grams.What is the half-life of the goo in minutes? Find a formula for G(t)G(t), the amount of goo remaining at time tt. How many grams of goo will remain after 32 minutes?arrow_forwardThe half-life of 1311 is 8.04 days.

From the symbol that is given, we know this is an isotope of Carbon, 6C12. The 6C14 can be substituted for 6C12 in chemical reactions in a cell because it has: (It's not Radioactive Properties) a) radioactive properties, b) 14 protons, c) ionic properties, d) 8 neutrons e) 6 electrons.arrow_forward
- Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years. While the medical community considers it to be reasonably safe, within the limits of testing, does this make sense considering both chemical and biological principles?
