A Century since Roentgen's Discovery of X-radiation and Radiation Protection.

X-Radiation and Gamma Radiation

Ionizing radiation is electromagnetic radiation that has sufficient energy to remove electrons from atoms. Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two categories: photons (X-radiation and gamma radiation) and particles (alpha and beta particles and neutrons). Five types or sources o...

X-radiation and Γ-radiation

Knowledge and practices concerning the effects of ionizing radiation and x-ray protection methods in dental offices in Babol, 2013

Introduction: As the absorption of radiation in environment is increasing, the present study was performed to evaluate the knowledge and practices of Babol’s dentists about x-ray protection . Materials &Methods: This cross-sectional study was designed to assess the knowledge and practices of dentists. The questionnaires were distributed among 70 dentists in Babol city. Analysis of the ...

Discovery of a Planar Waveguide for an X-Ray Radiation

This figure "pict2.png" is available in "png"" format from: A simple model of X-Ray standing waves (XSW) formation in the slit of a planar waveguide of X-Ray radiation beam for the angle area restricted by the critical total reflection angle is developed. It is shown that the model is true for a case of the Bragg reflection. The conditions required for XSW to appear in the space between two pol...
