The flow of radioactive particles inside the body from internally deposited radioisotopes in people exposed to inhalation, ingestion, injection, or other ways is usually evaluated using compartmental models. The biokinetic models included in the documents of the International Commission on Radiological Protection such as International Commission on Radiological Protection 66 and 78 involve many...

The development of two probabilistic accident consequence codes sponsored by the European Commission and the United States Nuclear Regulatory Commission, COSYMA and MACCS respectively, was completed in 1990. These codes estimate the risks and other endpoints associated with accidents from hypothesised nuclear installations. In 1991, both commissions sponsored a joint project for an uncertainty ...

Risks of serious hereditary damage in the first and second generations after low level radiation exposure and at equilibrium were calculated by using a doubling dose of 100 rem (based on experimental work with the mouse) and by considering separately the various categories of genic and chromosomal defect. Prenatal lethality has not been included. It is estimated that after the exposure of a pop...

African mine workers exposed to siliceous dust in the metalliferous mines of Northern Rhodesia were tuberculin tested; of 17,697 tested, 13,667 were tuberculin positive and 4,030 negative. The negative reactors were divided at random into two approximately equal groups and 1,984 were vaccinated with vole bacillus vaccine and 2,046 were left unvaccinated. These two groups were subsequently follo...

BACKGROUND Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. MATERIAL AND METHODS ...

INTRODUCTION The European Union has established specific directives concerning radiological protection which are obligatory for member States. In addition, all Spanish dental clinics with radiological equipment are required to have an annual quality control check. OBJECTIVE To analyze the effect of new European legislation on dental radiological practice in Spain and to determine whether it h...
