Electromagnetic Dosimetry. Electromagnetic dosimetry is the science of determining how much electric field ( dose) exists for specific sources and environments. It predicts the dose of the electromagnetic field present at any point inside or outside of the body.

The second part is the determination of the E and B fields inside an object exposed to the incident fields.
The relationship between the incident EM fields and the internal EM fields is a strong function of the frequency, the size and shape of the body, and the electromagnetic properties of the body.

In general, the penetration of incident fields into biological bodies decreases as frequency increases.
The skin depth is defined as the depth at which the EM fields have decreased to 1/e (i.e., 0.37) of their value at the surface of the body.
At optical frequencies, the penetration is very slight, and whatever effects the EM fields have on the body are primarily surface effects.
