External Dose Assessment

There are many variables that come into play when doing external dose estimation. Among the things to consider are time of exposure, distance from the source, source activity, potential shielding, and isotope. Some of these items are usually fairly straight forward, source activity and isotope, for instance. It is oftentimes much more difficult to be able to pinpoint the distance the affected area was from the source or the time of exposure. Due to distance vs. dose rate relationships these inconsistencies can have tremendous impacts on the dose estimates.
