How to calculate the exposure rate?

  1. Hello Everyone,

    I'm a student nurse in my last semester, and the topic is oncology nursing. There is an example of calculating the expousre rate:

    if exposure rate is 12m at 4ft what would exposure rate be at 8ft?
    the answer is 3

    I'm having a hard time trying to figure this one out? Any suggestions?

    I have been an oncology nurse for 8 years and have no idea what you're trying to do. Are you working on body surface area (BSA)? or on previous exposure to a specific drug? Why don't you post the entire question posed to you and maybe we can help.

    I've been in Oncology for close to ten years, worked in onco/hemo in 3 of the top hospitals in the country, and have no clue what the OP is asking.

    Could you please elaborate?

    ix d^2 = I x D^2

    so.. 12 x 4^2 = I x 8^2
    12x16=64I
    192/64=I

    I=3

    i and I = the two intensity values
    d and D= the two distance values

    I'm in school for nuclear medicine
