In recent years, a growing concern about the possible health hazards of mobile phones radiofrequency radiation has increased considerably among almost everyone in the world, even on those who do not have such phones. Moreover, new technologies, which use the spectrum of high frequency emissions, are incorporated in many aspects of telecommunications. As a consequence, there is a lot of interest...

The aim of this study was to provide data on genetic hazards associated with occupational exposure to low doses of ionising radiation in nuclear medicine departments. The DNA damage in peripheral blood lymphocytes of medical staff was assessed using the chromosome aberration test. Altogether 120 subjects (60 exposed and 60 controls) participated in the study. The exposed subjects showed signifi...

The Radiation Assessment Detector (RAD) on the Mars Science Laboratory's Curiosity rover began making detailed measurements of the cosmic ray and energetic particle radiation environment on the surface of Mars on 7 August 2012. We report and discuss measurements of the absorbed dose and dose equivalent from galactic cosmic rays and solar energetic particles on the martian surface for ~300 days ...

This study investigated the awareness and attitudes of basic surgical trainees. Trainees were asked to answer questions from a pre-set questionnaire. Fifty basic surgical trainees from England and Wales were involved in the study. The areas covered were basic knowledge of radiation hazards, use of protective wear, pregnancy test in female trauma victims of reproductive age, and principles of sa...

The flux of radiation particles encountered by a spacecraft is a phenomenon that can largely be understood statistically. However, the same cannot be said for the interactions of these particles with the spacecraft as they are far more challenging to grasp and guard against. The ultimate impact of a radiation particle’s interaction with a spacecraft depends on factors that often extend beyond t...
