Introduction Due to the increasing use of angiography procedures and the higher risk of deterministic and stochastic effects for radiation workers of these sections than other radiological procedures, radiation safety is very important in angiography staff. So, this study aimed to obtain the effective dose of angiography staff and compare them with the standard dose limit and finally outline th...
Radioprotectors are compounds that protect against radiation injury when given prior to radiation exposure. Mitigators can protect against radiation injury when given after exposure but before symptoms appear. Radioprotectors and mitigators can potentially improve the outcomes of radiotherapy for cancer treatment by allowing higher doses of radiation and/or reduced damage to normal tissues. Suc...
The issues related to protection against natural radiation at home and at work are addressed in the last fifteen years by various international organizations, professional bodies and national laws and regulations. The ICRP and the IAEA outlined theoretical principles, basic recommendations and some practical instructions for the classification of exposure situations to natural radiation sources...
Introduction In order to discharge the patients receiving treatment with large radiation doses of 131I for thyroid cancer, it is necessary to measure and evaluate the external dose rates of these patients. The aim of the study was to assess a new method of external dose rate measurement, and to analyze the obtained results as a function of time. Materials and Methods In this study, a telescopic...
The IAEA/RCA (Regional Cooperative Agreement) project to strengthen and harmonize radiation protection infrastructures in Asian and Pacific region started in 1988. The number of the RCA member countries is 17 at present. In the early stages of the project, there was little information on the status of radiation protection and their technical abilities of radiation protection measurements in RCA...
Introduction: one of the most important complications of exposure to ionizing radiation is emergence of cancer tumors, which happens as a result of oxidative DNA. Therefore, the present study was conducted, aimed to measuring 8-DIHYDROxy- 2’- DEOXYGUANOSINE (8-OHdG) level in radiographers’ urine as oxidative damage biomarker, as well as comparing this biomarker with cumulative effective doses....
Background: Radiology staff needs to justify the radiation exposures in order to protect themselves and others from radiation risks. The aims of this study were to examine the awareness level of radiation dose and protection amongst radiographers and to compare their performance between major Jordanian hospitals. Materials and Methods: A cross-sectional survey was conducted in 4 major Jord...
Evaluation of the application of the concepts of exemption and clearance for practices according to title III 2003 This report was produced by NNC Limited (Warrington, UK) for the European Commission and represents that organisation's views on the subject matter. These views have not been adopted or in any way approved by the Commission and should not be relied upon as a statement of the Commis...
