Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I've been reading about attenuation, and I wonder if there's a way to determine the distance to your source. Forgive my poor writing; I'm new to the topic.

I understand that equation for linear attenuation is

where:I = I_{0}e^{-μx}

I= intensity

I_{0}= initial intensity

μ= attenuation coefficient

x= distance traveled through medium

My question is this: if I have the informationμandI, is there some way to determinex, and/orI? It seems that I need to find either of those to find them both, so I wonder if there's some other measurements I could take that would make this possible._{0}

For a simple-minded example, would it be possible to take measurements of intensity at a variety of perpendicular distances in order to determine the geometric spreading and work backward from that to find distancex?

Thank you kindly for your time and knowledge.
