- So I just need help with the last question where it gives you the 160 The answer for the first question is 1.168 x 10^12 And the answer for the second one is 0.140 , i just need taht last one9)A drug has a half-life of 6 hours. The drug is administered by I/V injection, and immediately after administration its plasma level is 136mcg/ml. Results for a blood test later on show a plasma level of 8.55mcg/ml. How many half-lives have passed?The intensity of radiation at 10 ft was 200 R/hr. If the technologist moved to 5 ft from the source of radiation, what would the exposure be? O a. 400 R/hr Ob. 800 R/hr Oc. 100 R/hr Od, 50 R/hr
- 27. A shielded vial with a 1-mm thick lead shield contains Tc. If A. 11.8 mR/hr В. 23.5 mR/hr C. 47 mR/hr D. 94 mR/hr the unshielded sample yielded an exposure rate of 188 mR/hr, what will the exposure rate be from the shielded vial? (The lead HVL for Tc is 0.25 mm.) 28. If "Co gives an exposure rate of 38 R/hr at 2 m, at least how А. 2 В. 3 many HVLS of concrete shielding are required to reduce this exposure to below 2 R/hr at the same distance? (The concrete HVL for "Co is 6.2 cm.) С. 4 D. 5can you convert GPE into KE? if yes how ?
