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

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 $k x$ ...
