It shows an example where the distance from the radiation is reduced to 1/2. Using this information you are to calculate the change in intensity if the distance from the source is reduced to 1/4 instead of 1/2. I = Io/d2 where I = Intensity Io = Intensity at 1 ft d2 = distance from source squared (Suggestion,use a given distsance such as 40 ft as your reference and work from that point. ) What are you looking for: What do you need to answer the question(s)? Estimate what your answer(s) might be (think of both numbers and terms to be used) Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units used are correct) DSET|ÿÿ(Hÿÿÿÿÿÿå,œÔˆ=†9 ˆÔ6ÿÿ*=†9DSET¤ÿÿ(Hÿÿÿÿÿÿå,¬9ˆÔ9Ô?º6ÿÿ*=D9DSETR å,øå,üå-Ôå.¬   å+Unit 14 video problemFNTMTÿÿH HelveticaCUTS
