Alpha Therapy

AbstractWe present the guideline for use of [211At] sodium astatide (NaAt) for targeted alpha therapy in clinical trials on the basis of radiation safety issues in Japan. This guideline was prepared by a study supported by the Ministry of Health, Labour, and Welfare, and approved by the Japanese Society of Nuclear Medicine on 8th Feb, 2021. The study showed that patients receiving [211At]NaAt do not need to be admitted to a radiotherapy room and outpatient treatment is possible. The radiation exposure from the patient is within the safety standards of the ICRP and IAEA recommendations for the general public and caregivers. Precautions for patients and their families, safety management associated with the use of [211At]NaAt, education and training, and disposal of medical radioactive contaminants are also included in this guideline. Treatment using [211At]NaAt in Japan should be carried out according to this guideline. Although this guideline is applied in Japan, the issues for radiation protection and evaluation methodology shown here are considered internationally useful as well.

Abstract Background Limitations of tuberculosis (TB) diagnostic tools and measures restrict proper TB control in places with high drug-resistant TB prevalence. This study aimed to explore gaps in the primary health care (PHC) TB services in Armenia compared to international standards on Assessment of Patients (AOP). Methods We applied mixed methods to assess the AOP standards in 30 outpatient TB centers using observational and documents/medical records review's standardized checklists, in-depth interviews, and focus group discussions. Evaluation was conducted in all 10 regions of Armenia and the capital city Yerevan. Joint Commission International Standards for Ambulatory Care, International Standards for TB Care, and WHO framework, served as a guideline for this assessment. Results PHC physicians are qualified for a set of examinations to diagnose TB. Planned reassessments are conducted continuously, though defined writings for the scope and content of reassessments administered by each clinical discipline is absent. Laboratory departments provide high quality services to the TB patients with the defined timeframes for reporting the results. Laboratory and radiology services staff is qualified and experienced. The biosafety rules are compliant with local and international standards. However, the location and conditions of the laboratory departments are mostly non-compliant with the standards. Lack of modern equipment restricts maintaining proper environmental controls, including ventilation systems. Laboratory technicians have little knowledge of the organization's safety management program and its relation to the laboratory safety program. The facilities have neither formal quality control programs regulated by documents and policies nor an identified radiation safety program protocol. Conclusions On the level of AOP standards, the PHC TB services in Armenia have satisfactory performance. However, assessed standards for this function required certain improvements. Key messages In Armenia, the tuberculosis care in PHC facilities presents high level of compliance for patient assessment international standards. To fully meet the standards, facilities need to reconstructed/renovated laboratories and establish the radiology and diagnostic equipment management, quality control and radiation safety programs.

Abstract In this study, the radiation exposure of workers at workplaces registered and licensed between 2008 and 2017 for the production/sale/use of radioactive isotopes (RI) and radioactive generators (RG) was analysed to evaluate the quality of radiation safety management controls in use. The number of facilities using RIs increased by ~26% from 2008 to 2017 whereas the number of facilities using RGs increased by ~166% over the same period. There were 33 029 radiation workers in all fields in 2008, and the number increased by ~32% to 43 467 by 2017. However, the collective effective dose of radiation received by workers decreased in all industries except for those working in nuclear power plants. In other words, the quality of radiation safety management improved over that same time period due to the systematic, continuous introduction of safety mechanisms by the regulatory authority.

The task of radiation safety management by the optimization of protective structures parameters has been considered. The techniques for calculating the attenuation coefficient of radiation of multilayer floor slabs, the range of constructional materials and the method of the optimization calculation of multilayer protective structures have been analyzed. The analysis has shown that the achievement of the maximum possible efficiency of protection at random distribution of materials is improbable. The optimization task has been solved of the distribution of materials on protective structures and their constructional elements and the list of target functions and restrictions has been made. The algorithm and the program have been developed, the method of optimization calculation of a group of protective structures for the purpose of increasing personnel radiation safety has been improved, and the calculation data testifying the efficiency of the offered approach have been obtained.
