Радиационная защита биосферы, включая Homo sapiens: выбор принципов и поиски решения
Provedor de dados: 13
Autores: Поликарпов, Г. Г.
Представлен итог рассмотрения основных аспектов этой проблемы. Предлагается развернутая формулировка радиационной защиты биосферы: "Защищенная от вредного действия ионизирующих излучений биосфера обеспечит радиационную безопасность и полноценную жизнеспособность человечества" или кратко: "Защищена биосфера - защищен и человек".

Biosafety in veterinarian establishments in the city of Ribeirão Preto, Sp, Brazil
Provedor de dados: 195
Autores: Valente, Dario; Oliveira, Carlos Alberto d'Ávilla de; Rodrigues, Vânia Cantarela; Trebbi, Hélio.
Objective: To identify specific conditions in veterinary establishments that may jeopardize biosafety, such as: a) proper disposal of medical waste; b) compliance with radiological safety rules; c) use of personal protection equipment; d) pre-exposure vaccination of directly involved personnel against rabies and tetanus; e) utilization of a refrigerator exclusive for storage of biological products; j) use of Maximum-Minimum thermometer; g) employment of adequate disposal container. Material and Method: Retrospective study based on dala collected from sanitary inspection reports concerning requests for Operation License, filed within the Sanitary Surveillance section of the Municipal Health Secretariat of Ribeirão Preto, Sp, Brazil. The files of36...

Two decades of radiological accidents direct causes, roots causes and consequences
Provedor de dados: 52
Autores: Rozental,Jose de Julio.
Practically all Countries utilize radioisotopes in medicine, industry, agriculture and research. The extent to which ionizing radiation practices are employed varies considerably, depending largely upon social and economic conditions and the level of technical skills available in the country. An overview of the majority of practices and the associated hazards will be found in the &lt;A HREF="#tabela4"&gt;Table IV&lt;/A&gt; to &lt;A HREF="#tabela7"&gt;VII&lt;/A&gt; of this document. The practices in normal and abnormal operating conditions should follow the basic principles of radiation protection and the Safety of Radiation Sources, considering the IAEA Radiation Protection and the Safety of Radiation Sources, Safety Series 120 and the IAEA Recommendation...

Activities, procedures and doses in pediatric patients due to radiopharmaceuticals
Provedor de dados: 52
Autores: Oliveira,Silvia Maria Velasques de; Boasquevisque,Edson Mendes; Santos,Felipe Sima dos; Biancardi,Rodrigo.
An investigation performed between 2003 and 2005 in sixteen selected public and private institutions in Northeast, Southeast and South geographical regions of Brazil evaluated average organ doses and effective doses in 2,411 pediatric patients due to diagnostic procedures with radiopharmaceuticals. For 1 year, effective doses were greater than literature. For 5 years, differences were noticed between present work and literature for bone scintigraphy, thyroid scintigraphy and 67Ga citrate scintigraphy. These differences may be attributed to the uncertainties in internal dose calculations. High absorved doses in bone surfaces of children due to 67Ga citrate and bone scintigraphy should be evaluated accordingly. Current protocols used recommend standardized...

Internal exposure in nuclear medicine: application of IAEA criteria to determine the need for internal monitoring
Provedor de dados: 52
Autores: Dantas,Bernardo Maranhão; Lucena,Eder Augusto de; Dantas,Ana Letícia Almeida.
The manipulation of unsealed sources in nuclear medicine poses significant risks of internal exposure to the staff. According to the International Atomic Energy Agency, the radiological protection program should include an evaluation of such risks and an individual monitoring plan, assuring acceptable radiological safety conditions in the workplace. The IAEA Safety Guide RS-G-1.2 recommends that occupational monitoring should be implemented whenever it is likely that committed effective doses from annual intakes of radionuclides would exceed 1 mSv. It also suggests a mathematical criterion to determine the need to implement internal monitoring. This paper presents a simulation of the IAEA criteria applied to commonly used radionuclides in nuclear medicine,...
