Radiation safety is an important counterpart in all facilities utilizing ionizing radiations. The concept of radiation safety has always been a hot topic, especially with the late reports pointing to increased hazards with chronic radiation exposure. Adopting a nationwide radiation safety program is considered one of the most urging topics, and is a conjoint responsibility of multiple disciplin...

OBJECTIVE To investigate if the levels of optical radiation hazards in glassblowing are well classified according to the hazard types defined in the Canadian Standards Association (CSA) standard for industrial eye protectors. METHODS We carried out radiometric measurements, and questionnaire survey in 4 university glassblowing laboratories, and 3 private studios. RESULTS There is exposure t...

background: although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. it is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. the purpose of this study has been to investigate the level of physicians' knowledge about r...

Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...

the harmful effects of the long-term ocular exposure to cumulative levels of infrared radiation (ir) in glassblowing and foundries have been recognized since the late 19th century. these effects include cataracts, keratitis, and chronic dry eye problems. therefore, infrared radiation measurements are critical and need to be assessed regularly in the industries and workplaces where there are hig...

background: to assess the status of occupational hazards and their prevention among the practicing dentists in chandigarh city, india. materials and methods: a closed-ended questionnaire was prepared to record demographic status, types of occupational hazards encountered, and status of measures used for their prevention. a total 113 out of 130 dentists completed the questionnaire and the respon...

The Janus series of radiation experiments, conducted from 1970 to 1992, explored the effects of gamma and neutron radiation on animal lifespan and disease development. Data from these experiments presents an opportunity to conduct a large scale analysis of both tumor and non-tumor disease development. This work was focused on a subset of animals from the Janus series of experiments, comparing a...

Investigators at several laboratories are seriously considering the storage and transport, perhaps over long distances, of very low energy antiprotons as a part of basic physics research programs and perhaps even for practical applications. To do this will require proper attention to the prompt radiation hazards due to the release of energy in the annihilations of antiprotons with nuclei, under...
