Description: The focus of this Report is on uncertainties associated with measurement techniques and the estimation of organ absorbed doses (DT) from exposure to external radiation sources.
This Report is the first in a planned series on uncertainty in radiation measurements and dosimetry. Its focus is on external radiation. The second in this series will focus on internal dosimetry, and the third report will discuss fundamentals of dose reconstruction. A fourth report on uncertainty in risk and probability of causation is also planned.
The objective of this Report is to review the current state of knowledge
of uncertainties in external radiation measurements and dosimetry, and in the conversion coefficients used to relate such measurements to absorbed dose in the human body. The focus is on the uncertainties in measurements of beta, gamma and neutron radiation from sources external to the body and the conversion of the measured quantities to organ absorbed doses (DT).
