Abstract
A combined measuring and computing method is given by means of which the Committed Effective Dose Equivalent can be estimated. A sensitive detector equipped with a suitable collimator moving along the length of a person being investigated, enables the count rate profile to be obtained from which organ activities can be deduced. With repeated measurements the activity time variations and their time integrals can be derived, the latter being proportional to the organ doses. The general description of the methods and its implementation in the radiation protection practice of the Central Research Institute for Physics is given. Test experiments show the method to be suitable for internal dose assessment when the activity exceeds 0.5 kBq per organ.
