introduction natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. radionuclides can affect human health by transferring from soil to plants and entering the human body. in this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...

OBJECTIVES To analyze the results of an initiative aimed at improving the reasonable use of radiological examinations, ensuring their technical quality, implementing a radioprotection campaign that includes training of the professional team, and introducing the radioprotection card for children under 12 years old as a tool for parents and doctors to control children's exposure to radiation. M...

background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...

Background: In response to the need for diagnosis and treatment, medical radiation has been increasingly used worldwide. This study investigated the medical utilization of radiation-related diseases among radiological technologists (RTs) and factors that influence such diseases. Materials and Methods: Data were collected from the Taiwan National Health Insurance Research Database. A panel study...

Advanced imaging technology has opened new horizons for medical diagnostics and improved patient care. However, many procedures are unjustified and do not provide a net benefit. An area of particular concern is the unnecessary use of radiation when clinical evaluation or other imaging modalities could provide an accurate diagnosis. Referral criteria for medical imaging are consensus statements ...

Natural and artificial ionizing radiation can be harmful to human health when they come into contact with people the environment. Transport of naturally occurring radioactive materials (NORMs) consumer products containing NORM in public domain is inevitable owing their potential applications. This study evaluates dose risk from transport accidents products. Radiological physical data were obtai...

Radiological terrorism (radioterrorism) is the deliberate use of radiological weapons. These weapons use radioactive materials to disperse and emit ionizing radiation. There are two classes of radiological weapons - radiological dispersal devices (RDD) and radiation emission devices (RED). These weapons would no cause massive numbers of dead. In most radiological attack scenarios, only few peop...

Some Areas of Ramsar, a city in northern Iran are among the world’s wellknown inhabited areas with highest levels of natural radiation. Annual exposure levels in these areas are up to 260 mGy y‐1 and the mean exposure rate is about 10 mGy y‐1 for a population of about 2000 residents. If elevated levels of natural radiation as high as a few hundred mSv per year is detrimental to health and...

X-rays or computed tomography (CT) scans are performed frequently in the hospital for health examination or treatment purposes. Medical radiation involves applying radiation such as X-rays, gamma-rays, or beta rays, injecting radioactive isotopes into the body, or administering them orally to take imaging studies or treat diseases such as cancer. When the human body is exposed to radiation, cel...
