The use of radiation as a diagnostic instrument, and the biological effects of irradiation have received so much scrutiny during the past decade that exposure to radiation has become a public interest concern. Most lay persons, that is nonscientists, perceive radiation exposure as possibly injurious. Knowledge of possible radiation effects has become so generally dissiminated that most lay pers...
Radiation fireballs are singular phenomena which involve severe thermal radiation and, consequently, they need to be duly assessed and prevented. Although the radiative heat transfer produced by a sphere is relatively well known, shadowing measures implemented control fireball’s devastating effects have frequently posed difficult analytical instance, mainly due its specific configuration. The o...
Radiation is any kind of energy transmitted without an intermediate medium. Radiant generally wave-shaped, most commonly sinusoidal. There are two types radiation: ionizing radiation and non-ionizing radiation. Ionizing that causes the process ejecting electrons from atoms to form ion pairs. Attention should be paid radiation, particularly its sources, types, properties, effects, methods avoida...
OBJECTIVE In this study, we evaluated the knowledge and perception and mitigation of hazards involved in radiological examinations, focusing on healthcare personnel who are not in radiation-related occupations, but who use ionising radiation as a part of their work. METHODS A questionnaire was applied to physicians, nurses, technicians and other staff working in different clinics that use rad...
Introduction: Dental students, during their clinical and preclinical practices, are constantly exposed to a number of occupational hazards. Such exposures lead various ailments diseases. The study was done assess the awareness regarding hazards among dental students in College Medical Sciences, Nepal. Methods: A questionnaire-based, descriptive cross-sectional conducted from Demographic details...
Background:In diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. Lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiology range.Objective: Although lead aprons have good radiation protection properties, in recent years, researchers have been looking for altern...
Solarium or tanning machines are available at gyms, beauty salons and.... Now, it is about 35 years since these devices have been introduced for tanning with ultraviolet radiation (UV). UV radiation having chemical reactions with skin, increases skin pigmentation and helps the formation of vitamin D and calcium absorption. Using solarium in Europe where they get less benefit from direct sunligh...
