IAEAL 06–00417 This publication has been superseded by SSG-46. FOREWORD The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS) cover the application of ionizing radiation for all practices and interventions and are, therefore, basic and general in nature. Users of radiation sources have to apply these basic requirements to their own particular practices. This requires a degree of ‘interpretation’ by the user, which can result in varying levels of regulatory compliance and inconsistencies between applications of the BSS to similar practices. In this context, the preamble of the BSS states that: “The [regulatory body] may need to provide guidance on how certain regulatory requirements are to be fulfilled for various practices, for example in regulatory guideline documents.” In order to guide the user to achieve a good standard of protection and to achieve a consistent national approach to licensing and inspection, some countries have developed practice specific regulatory guidance, while others have practice specific regulations. For obvious reasons, national regulatory guidance is tailored to a country’s own legislation and regulations. This can lead to problems if the guidance is used in other States without appropriate modification to take local requirements into account. There would therefore appear to be scope for producing internationally harmonized guidance, while bearing in mind that the ultimate responsibility for the regulatory documents rests with the State. Some regions have taken the initiative of preparing guidance to facilitate the regional harmonization of regulatory control of certain common practices (e.g. radiotherapy). A number of draft regulatory guidance documents for the main practices involving the use of ionizing radiation have already been prepared. This initiative indicates that there is a global demand for such documents. In particular, it is felt that countries participating in the IAEA’s technical cooperation model project on Upgrading Radiation and Waste Safety Infrastructure would benefit significantly from the availability of practice specific guidance. Member States could then more readily develop their own guidance tailored to their own requirements and needs. This idea led to the development of the present report. The Action Plan on the Radiological Protection of Patients, approved by the IAEA General Conference in September 2002, requires that “The practice- specific documents under preparation should be finalized as guidance rather than regulations, and they should include input from professional bodies, from international organizations and from authorities with responsibility for radiation protection and medical care.” Following this request, the only This publication has been superseded by SSG-46. mandatory statements of this report are quotations from the BSS, including requirements. There are certain BSS requirements that, when applied to specific practices, can be fulfilled mainly through one practical solution. In these cases, the regulatory body may need to use a ‘should’ statement, which implies that licensees should choose this solution or, if another option is intended, an equivalent level of safety should be provided. In other cases, there may be more than one option. In these cases the regulatory body would just mention or describe them. This guidance is intended for both regulators and users of radiation sources in radiotherapy. Regulators may use it for reviewing applications for authorization and during the inspection of facilities. Registrants/licensees may wish to follow the guidance in order to comply with BSS requirements or equivalent national requirements. Experts recruited on IAEA missions to advise on the implementation of the BSS for the practice of radiotherapy are expected to use this regulatory guidance report rather than their own national guidance. Working safely, with a quality assurance programme, is important and contributes to gaining overall confidence and credibility in the practice of radiotherapy. This report has been prepared by the IAEA with the contributions of the Pan American Health Organization, the International Labour Office, the World Health Organization, the European Society for Therapeutic Radiology and Oncology and the International Organization

  • Internal Radiation Therapy, Places Radioactive Material Directly Inside Or Next to the Tumor
    Brachytherapy Brachytherapy is a type of radiation therapy used to treat cancer. It places radioactive sources inside the patient to kill cancer cells and shrink tumors. This allows your doctor to use a higher total dose of radiation to treat a smaller area in less time. Your doctor will tell you how to prepare and whether you will need medical imaging. Your doctor may use a computer program to plan your therapy. What is brachytherapy and how is it used? External beam radiation therapy (EBRT) directs high-energy x-ray beams at a tumor from outside the body. Brachytherapy, also called internal radiation therapy, places radioactive material directly inside or next to the tumor. It uses a higher total dose of radiation to treat a smaller area in less time than EBRT. Brachytherapy treats cancers throughout the body, including the: prostate - see the Prostate Cancer Treatment (https://www.radiologyinfo.org/en/info/pros_cancer) page cervix - see the Cervical Cancer Treatment (https://www.radiologyinfo.org/en/info/cervical-cancer-therapy) page head and neck - see the Head and Neck Cancer Treatment (https://www.radiologyinfo.org/en/info/hdneck) page skin breast - see the Breast Cancer Treatment (https://www.radiologyinfo.org/en/info/breast-cancer-therapy) page gallbladder uterus vagina lung - see the Lung Cancer Treatment (https://www.radiologyinfo.org/en/info/lung-cancer-therapy) page rectum eye Brachytherapy is seldom used in children. However, brachytherapy has the advantage of using a highly localized dose of radiation. This means that less radiation is delivered to surrounding tissue. This significantly decreases the risk of radiation-induced second malignancies, a serious concern in children.

  • Standards for Radiation Oncology
    Standards for Radiation Oncology Radiation Oncology is the independent field of medicine which deals with the therapeutic applications of radiant energy and its modifiers as well as the study and management of cancer and other diseases. The American College of Radiation Oncology (ACRO) is a nonprofit professional organization whose primary purposes are to advance the science of radiation oncology, improve service to patients, study the socioeconomic aspects of the practice of radiation oncology, and provide information to and encourage continuing education for radiation oncologists, medical physicists, and persons practicing in allied professional fields. As part of its mission, the American College of Radiation Oncology has developed a Practice Accreditation Program, consisting of standards for Radiation Oncology and standards for Physics/External Beam Therapy. Accreditation is a voluntary process in which professional peers identify standards indicative of a high quality practice in a given field, and which recognizes entities that meet these high professional standards. Each standard in ACRO’s Practice Accreditation Program requires extensive peer review and the approval of the ACRO Standards Committee as well as the ACRO Board of Chancellors. The standards recognize that the safe and effective use of ionizing radiation requires specific training, skills and techniques as described in this document. The ACRO will periodically define new standards for radiation oncology practice to help advance the science of radiation oncology and to improve the quality of service to patients throughout the United States. Existing standards will be reviewed for revision or renewal as appropriate on their third anniversary or sooner, if indicated. The ACRO standards are not rules, but rather attempts to define principles of practice that are indicative of high quality care in radiation oncology.

  • The Impact of County-Level Radiation Oncologist Density on Prostate Cancer Mortality in the United States
    Prostate Cancer and Prostatic Diseases (2012) 15, 391 -- 396 & 2012 Macmillan Publishers Limited All rights reserved 1365-7852/12 www.nature.com/pcan ORIGINAL ARTICLE The impact of county-level radiation oncologist density on prostate cancer mortality in the United States S Aneja1 and JB Yu1,2,3 BACKGROUND: The distribution of radiation oncologists across the United States varies significantly among geographic regions. Accompanying these variations exist geographic variations in prostate cancer mortality. Prostate cancer outcomes have been linked to variations in urologist density, however, the impact of geographic variation in the radiation oncologist workforce and prostate cancer mortality has yet to be investigated. The goal of this study was to determine the effect of increasing radiation oncologist density on regional prostate cancer mortality. METHODS: Using county-level prostate cancer mortality data from the National Cancer Institute and Centers for Disease Control as well as physician workforce and health system data from the Area Resource File a regression model was built for prostate cancer mortality controlling for categorized radiation oncologist density, urologist density, county socioeconomic factors and pre-existing health system infrastructure. RESULTS: There was statistically significant reduction in prostate cancer mortality (3.91--5.45% reduction in mortality) in counties with at least 1 radiation oncologist compared with counties lacking radiation oncologists. However, increasing the density of radiation oncologists beyond 1 per 100 000 residents did not yield statistically significant incremental reductions in prostate cancer mortality. CONCLUSIONS: The presence of at least one radiation oncologist is associated with significant reductions in prostate cancer mortality within that county. However, the incremental benefit of increasing radiation oncologist density exhibits a plateau effect providing marginal benefit.

    Vol-6 Issue-3 2020 IJARIIE-ISSN(O)-2395-4396 Burning of Body: Causes, Stages, Effects, Preventions Parul Gupta CT University Abstract Burn in one of the most destructive form of trauma. A burned body show many changes in the physical and chemical properties of the body parts. Burn can be caused in different ways: Thermal, Chemical, Electrical, Radiation, Sunburns, Cold burn and Friction burn. There are three stages of Burn which include: First degree, Second degree and Third degree. The burning cause the effects on the physiological as well as psychological factors. We need to take various precautions in order to prevent the injury cause due to the burning. Keywords : Burn , Body , Skin , Injury Burn is one of the most destructive form of trauma. This is a significant cause of injuries which may result in death of the person. This may also cause permanent functional impairment which not only effect the life of the victims but also their families and locality.[2] Most of the deaths are realted to the sepsis from burn wound because it further provide site for many infections. In case of serious injury, there is a need of special resources that minimize morbidity and mortality.[1] The special resources include specialized medical equipment, well educated staff and a well-organized systems for proper maintenance.[2] A burned body show many changes in the physical and chemical properties of the body parts. Depending upon the temperature of exposure heat, the manner of identification matters. In forensics, to examine burned body various techniques are used i.e.Anthropological tests, DNA profiling, Polymerase chain reaction.[3] Figure 1: Burned Vicitm Causes of Burns The burns can be classified on the basis of manner used: [5] [6] Thermal Burns: These Burns are caused due to the excess amount of heat which may occur due to steam, flames, hot water, hot area etc.

Chief Censor Radiation Oncology Clinicians who specialise in Radiation Oncology play an integral role in the complex multidisciplinary team management of cancer patients. Their practice is strongly underpinned by a detailed knowledge of the biological effects and physics of radiation, of pathology and anatomy as they relate to cancer and its control, and of the application of sophisticated imaging and treatment technologies. Paramount is an extensive understanding of all clinical aspects of cancer management. Radiation Oncologists are trained to be competent beyond their role as clinical and technical experts.
