This is a non-trivial question when it comes to radiation dosimetry. The determination of absorbed dose or dose equivalent is often more than an academic exercise or a research project. In the medical application of ionising radiation, the difference between a dose delivered to a tumour being too low or too high can result in either a recurrence or complications due to late effects. In this case, the dose has to be just right. And, the degree of just-rightedness may require the combined standard uncertainty (with no coverage factor) to be just a few percent. If the radiation is being used to sterilise disposable medical products, a similar situation can occur, although the required uncertainty may be somewhat larger. Too
