1. An accident has occurred in a uranium fuel processing plant and 3 workers are exposed to significant acute radiation dose.  

• Worker A receives whole body absorbed doses of 3 Gy of 2 MeV neutrons and 5 Gy of 1 MeV photons
• Worker B receives a whole body absorbed dose of 8.0 Gy photons
• Worker C receives a whole body absorbed dose of 1 Gy from 1.0 MeV photons.

All three workers are hospitalized.

1. What symptoms do you expect to observe, and when, in each worker?
2. What can you say about the likelihood of death for each worker?

Potassium permanganate (KMnO4) is sometimes added to water as it enters a drinking water treatment plant to assist in the removal of Fe2+ and Mn2+ ions. The KMnO4 oxidizes those cations by acquiring electrons according to the following reaction: KMnO4 + 4H+ + 3e ↔ K+ + MnO2(s) + 2H2O a) What is the (electron) equivalent weight of Mn, based on this reaction? b) Calculate the mass (g) of KMnO4 in 2 L of a 0.15 M KMnO4 solution. c) If 1.0 mL of 0.15 M KMnO4 is added to each liter of the drinking water, and all the KMnO4 undergoes the reaction shown above, what concentration of KMnO4 will be generated by the reaction, in ppm?

1. What is the % by mass of Mg2+(aq) in the 0.00500 M MgCl2(aq) solution from Question 1(0.00500 M)?  Assume the solution density is 1.0 g/mL, like water. (3 significant digits, unit %)
2. Kemmi dilutes the 26 ppm Ag+(aq) solution by twice pipetting 15 mL of solution into a 100 mL volumetric flask. She fills the remaining volume with water. Use M1V1 = M2V2 with M1 equal to 26 ppm. Solve for the diluted concentration (M2) in units of ppm. (2 significant digits, unit ppm)
(the molarity of the silver cation (Ag+) in the solution = 0.00024 M)
