What Form of energy is present in UV radiation ?

What are the advantages and disadvantages for bisphenols, halogens, alcohols, and heavy metals?

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? What are possible ways that you might deal with or…
