Compute the effective radiation dosage (in Sieverts) for a 67kg person who is exposed to 6.9*10^9 particles of alpa radition. Presume that 77% of the radiation is absorbed, each alpha particle has an energy of 6.6*10^-13 J, and that the RBE of the alpha particles is 15. Note that RBE is sometimes call the quality factor, abbreviated as Q.
Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent based solely on each element's position on the periodic table: P-P, Ca-O, Al-N, O-Br, S-Br, F-F, P-Cl, Cs-Cl
