If the exposure rate 0.6 mR/hr, what would it be after a month?
Calculate the specific exposure rate constant, in units of mR/hr at one meter for a 1 curie source, for Cesium-137 which emits a 0.662 MeV gamma ray in 94% of the disintegrations.
A therapy patient gave an exposure reading of 125 mR / hr at 1 meter. If a nurse spends 1.5 hours every day at the 2 mR / hr distance, 10 minutes every day at 1 meter, and 35 minutes every day at 2 meters, her total approximate exposure (in mR) over 4 working days is: A. 168 B. 156 C. 42 D. 11 E. 132
Compute the exposure rate in inGy/hr at a distance of 50 cm from a small vial containing 10 mL of an aqueous solution of 2 GBq (54.1 mCi)^51 Cr 2 GBq (54.1 mCi)^24 Na

How many curies of Np238 will there be in 1.00 gm Np237 after exposure to a thermal-neutron flux of 1.00 x 1011 cm-2sec-1 for 10 min, 10 hr, 30 hr, 60 hr, 100 hr, 300hr? Graph these values and estimate the time to reach half the limiting value.
(1)(a)What is exchange rate risk? Distinguish between Transaction Exposure and Economic exposure to exchange rate movements. (b)Consider the following information: 90-day U.S interest rate..... ..4% 90-day Malaysian interest rate.. .3% 90-day forward rate for the Malaysian Ringgit $0.400 Spot Rate of Malaysian Ringgit ..$0.404 Assume a U.S based MNC will need 300,000 Ringgit in 90 days and wishes to hedge this payable position. Would it be better off using a FORWARD hedge or MONEY MARKET hedge?
HR Industries (HRI) has a beta of 1.8, while LR Industries' (LRI) beta is 0.6. The risk-free rate, rRF, is 6%, and the required rate of return on an average stock is 13%. The expected rate of inflation built into rRF falls by 1.5 percentage points, the real risk-free rate remains constant, the required return on the market falls to 10.5%, and all betas remain constant. After all of these changes, what will be the difference in the required returns...
