Briefly describe the adverse effects caused by exposure to radiation. Include some specific exposure levels associated with these significant health effects.
Lastly, give some examples of measured radiation levels associated with the Three Mile Island incident in the U.S. and in the Chernobyl incident in the Soviet Union. Provide your reference source(s). (Wikipedia is not an accepted reference source.)

When using 95% ethanol, the rf value for methylene blue was a lot larger than the rf value for fluorescine. Why does this happen
What organic product(s) is formed when 1-methylcyclopentanol is heated in the presence of an acid catalyst?
The Neumann-Kopp law is a generalized experimental finding that the heat capacity of a substance can be well approximated by the sum of the heat capacities of the constituent elements, weighted by their contribution to the total composition.
If the ionization energy for rubidium is 403 kJ/mol . The electron affinity for iodine is -295 kJ/mol. Utilize these values and Hess's law to compute the enthalpy for the following reaction
