Question

Which is the most likely mode of radioactive decay for the radioactive Euclid carbon- 4? A) beta emission B) alpha emission C) emission D) electron capture E) emission Which of the following correctly represents the relationship among rads, sems, and relative biological effectiveness RBEY? A) rems = rads times RBE B) rems = rads times RBE C) rems = rads times RBE D) rads = rems times tar RBE E) none of these when 215_U collides with ose neutron fission occurs. What is one possible set of products? A) three neutrons Kr, and X_e B) three neuters 94_Kr, and C_e C) three neutrons, 91_Kr, and 135 D) three neutrons, E) three neutrons, Kr, What assumption must be tree for A) 14_C always decays at the same rate. B) Historically, there has always been the same amount of 54_C in the atmosphere as there is now. C) 54_C has the same mass as C. D) The sample cannot have been chemically altered prior to the analysis. E) C is nonradioactive.

Explanation / Answer

1 - A (beta emission)

2- B (rem = rads x RBE)

3- D (235U + 0n---------> 92Kr + 141Ba + 3 0n )

4- B
