Does the equation N = No e¯kt represent Radiation Strength?

  1. Mar 3, 2015 #1
    1. The problem statement, all variables and given/known data
    Given that we are working with biological samples of 5 and 10cm, is our assumption that the equation N = No e¯kt
    represents the radiation strength accurate? Explain.

    2. Relevant equations
    N = No e¯kt

    3. The attempt at a solution
    I'm completely stuck but...

    I believe it represents the transmission of a radiation beam through a given thickness of biological tissue. Sounds like radiation strength to me :c

    Please help?

    When you have a decay process, like light propagating inside something, and gets absorbed, you can either assume that the decay to be exponential or poissonian. This depends on the product ##k x## ...
