Radiation detriment is a basic measure which currently applied to assess health risks caused by exposure ionizing radiation. This concept was developed the International Commission on Radiological Protection (ICRP) more than 30 years ago; it has both certain advantages and drawbacks that limit scope of its possible application. A drawback this value used exclusively effects produced radiation t...

The United States radiation medical countermeasures (MCM) programme for radiological and nuclear incidents has been focusing on developing mitigators for the acute radiation syndrome (ARS) and delayed effects of acute radiation exposure (DEARE), and biodosimetry technologies to provide radiation dose assessments for guiding treatment. Because a nuclear accident or terrorist incident could poten...

Radiological imaging is an important part of today’s overall healthcare practicum and chest xrays are the number one exam performed. Imaging can begin as early as the first day of life but only recently have the effects of ionizing radiation on the pediatric population been brought to the forefront. Radiation effects are cumulative and children are more susceptible to cell damage therefore it i...

Introduction: Human beings are naturally exposed to ionizing radiation in any environment. There are two main contributors to radiation exposures from natural sources: cosmic rays, Cosmo genic radionuclides, and radioactive nuclides that originated in the earth's crust. According to the latest data provided by the United Nations Scientific Committee on the Effects of Atomic Rad...

Radiological and nuclear devices may be used by terrorists or may be the source of accidental exposure. A tiered approach has been recommended for response to a terrorist event wherein local, regional, state and federal assets become involved sequentially, as the magnitude in severity of the incident increases. State-wide hospital plans have been developed and published for Connecticut, New Yor...

Committee 3 of the International Commission on Radiological Protection (ICRP) develops recommendations and guidance for protection of patients, staff, and the public against radiation exposure when ionising radiation is used for medical diagnosis, therapy, or biomedical research. This paper presents a summary of the work that Committee 3 has accomplished over the past few years, and also descri...

background: the natural radionuclides are always present in soil and care needs to be taken to minimize the radiation dose to humans. these radionuclides are mostly gamma ray emitting radionuclides which contribute to the radiation dose in long term behavior of radionuclides in soil. health hazards associated with natural radioactivity are of great concern and it is necessary to assess risk due...

BACKGROUND In recent decades, patients' exposure to ionising radiation (IR) during diagnostic examinations has increased a great deal. X-ray requests do not always conform to the principle of 'justification', which emphasises the real utility and necessity of the examination. Databases maintained by general practitioners usually record all requests for radiological examinations of their patient...

INTRODUCTION The objective of radiation safety assessment of an operating nuclear power plant (NPP) is to assure that the licensee’s radiation protection program (RPP) has achieved the goal of radiation protection. For this, currently Korean regulatory safety inspection program is aimed at ensuring compliance with licensing requirements and regulations. The legislation requires that inspections...
