Radiation dose to the nuclear medicine nurses
Background: People who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. The aim of this work was to estimate radiation dose received by nuclear medicine nurses. Materials and Methods: In this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...
متن کاملEstimating radiation dose from building materials
Background: Natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. So, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. Materials and ...
متن کاملRadiation Dose Reduction Techniques in the Workplace
The principal objective of radiation protection is to ensure that the dose received by any individual does not exceed the applicable M.P.D. values.We will discuss in this paper the presents recommendations and technical information related to the design and installation of structural shielding with taking into account the concept of Maximum Permissible Dose equivalent (MPDl as expressed and ...
متن کاملBioburden and theoretical sterility dose calculation for radiation sterilization of surgical cotton and bandages.
The initial bioburden, count of colony forming unit (CFU) was determined on the locally manufactured non-sterilized surgical cotton and bandages. In all 489 tests were conducted on 163 cotton samples and 246 tests on 82 bandage samples. The surgical cotton showed an average of 198 microbes with a maxima of 287 and minima 94 whereas bandages showed an average of 179 microbes with a maxima of 268...
متن کاملValidation of 11 kGy as a radiation sterilization dose for frozen bone allografts.
A radiation sterilization dose (RSD) of 25 kGy is deleterious to bone allografts. This study aimed to establish a lower RSD for bone allografts using method 1 of International Standard Organisation 11137.2:2006. This provides a database to select an RSD corresponding to an allograft's bioburden, given that the bioburden's gamma resistance is equal to or less than the standard. This can be verif...
