Uncertainties in internal dose calculations for radiopharmaceuticals.
This paper presents a systematic analysis of the inherent uncertainty in internal dose calculations for radiopharmaceuticals. A generic equation for internal dose is presented, and the uncertainty in each of the individual terms is analyzed, with the relative uncertainty of all terms compared. The combined uncertainties in most radiopharmaceutical dose estimates will be typically at least a fac...
متن کاملCommitted Effective Dose from Thoron Daughters Inhalation
INTRODUCTION Mankind has been constantly exposed to radiation by natural radioactivity, nuclear tests, medical applications and nuclear energy activities. The natural radioactivity is the main component to human exposure and it is recognized that the most important contributors to the committed effective dose received by population due to natural sources are the short-lived decay products of ra...
متن کاملEffective dose to adult patients from 338 radiopharmaceuticals estimated using ICRP biokinetic data, ICRP/ICRU computational reference phantoms and ICRP 2007 tissue weighting factors
BACKGROUND Effective dose represents the potential risk to a population of stochastic effects of ionizing radiation (mainly lethal cancer). In recent years, there have been a number of revisions and updates influencing the way to estimate the effective dose. The aim of this work was to recalculate the effective dose values for the 338 different radiopharmaceuticals previously published by the I...

1. For 79 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” Should be “For 63 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” 2. “As a mean for all radiopharmaceuticals, the effective dose was 25 % lower.” Should be“As a me...
متن کاملEffective dose from natural background radiation in Keffi and Akwanga towns, central Nigeria
Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...
