Can someone explain the inverse square relationship in radiation because it is confusing?
As you get farther from the source of the radiation, the surface area of the sphere surrounding that source gets larger and larger by the factor R^2, where R is the radius of the sphere that marks the distance between the source of the radiation and the spot where the radiation is measured. The strength of radiation at R when the source is Q is called its field strength q = Q/A = Q/(4pi R^2) where A is the surface area of the sphere surrounding the source at radius R. As you can see, the field strength is a density property; in this case the density of the source radiation spread over a surface area. As R gets bigger, meaning as we get farther away from the source, the surface area A gets larger by a factor of R^2. So the field strength q = Q/A gets smaller as we get farther away because the A is increasing while the Q remains fixed. This means the density, the field strength, is getting thinner and weaker. We can compare field strengths at different distances R from the source. Let th
