Nuclear Fluorescence Using High-energy Synchrotron Radiation

We present some measurements of nuclear fluorescence which were made while exploring the potential of a unique source of very hard x-rays which was installed at ESRF until recently. It produced radiation of energies up to 1MeV. In this range there are many nuclear resonances, and so we made a small survey of some plausible candidates to see if they could indeed be excited using this source. Alo...

Radiation Physics and Chemistry

We review an atomic resolution imaging method based on the analysis of the fine structure in X-ray absorption anisotropy, which results from incident beam diffraction. For a polychromatic X-ray beam, due to the suppression of higher order diffraction fringes, X-ray absorption anisotropy patterns can be interpreted as distorted real-space projections of the atomic structure around absorbing atom...

Nuclear Radiation and Thyroid Cancer; A Systematic Review

Background: The increasing prevalence of thyroid cancer among the survivors of atomic bomb attacks in Japan, nuclear fallout in the Marshall Islands, and Chernobyl nuclear power plant accident indicate a strong relationship between nuclear radiation and the occurrence of thyroid cancer. Materials and Methods: Systematic researches were conducted in the medical database of the American National ...

Radiation dose to the nuclear medicine nurses

Background: People who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. The aim of this work was to estimate radiation dose received by nuclear medicine nurses. Materials and Methods: In this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...
