BACKGROUND/AIMS Recently, several studies have revealed that diagnostic imaging can result in exposure to harmful levels of ionizing radiation in inflammatory bowel disease patients. However, the extent of radiation exposure in intestinal Behcet disease (BD) patients has not been documented. The aim of this study was to estimate the radiation exposure from abdominal imaging studies in intestina...

The harmful effects of ionising radiation are widely acknowledged. It has been reported that young children, particularly girls, have a higher sensitivity to radiation than adults. However, the exact detrimental effects of radiation, particularly at the low doses used in routine diagnostic radiography, are unknown and the subject of much controversy. Computed tomography (CT) accounts for about ...

Ionizing radiation interacts with biological systems to produce reactive oxygen species and reactive nitrogen species which attack various cellular components. Radio-protectors act as prophylactic agents to shield healthy cells and tissues from the harmful effects of radiation. Past research on synthetic radio-protectors has brought little success, primarily due to the various toxicity-related ...

The first article in this series covered radiation hazards and protection. To minimize the potential harmful effects of X-rays, legislation has been introduced by a number of countries including the European Union.

The study of radiation absorption in material is an important subject to protect living creatures and environment from harmful effect of radiation. The degree to which gamma radiation is attenuated is dependent upon the energy of the incident gamma radiation, the thickness of the shielding, the atomic number and density of the elements in the shielding material. In this respect, this study pres...

X-rays are electromagnetic (EM) radiation with characteristics of short wavelengths, very high frequencies and very high energy. High energy EM radiation exhibits characteristics of both waves and discrete bundles of energy called photons. X-ray photon energy is usually measured in kilo-electron volts (keV) and diagnostic x-ray energies are typically 10 to 150 keV. Such high energy EM radiation...

The prevailing view of regulatory agencies and advisory groups is that all radiation is bad for health, and exposure to any form of it should be minimized. While high-dose radiation, regardless of source or intention, is harmful to health, evidence is presented that chronic doses up to 100 times those of normal ambient (including medical) exposures are beneficial, mainly due to lower cancer rat...

Background: Recently, there have been many studies on the harmful effects of radiation and the regulations on radiation safety have been toughened both at the in nation and abroad. This study aims to identify the perceptions and actions taken as to radiation safety, and the degree of knowledge related to radiation held by the radiologists working in large hospitals. Materials and Methods: ...

  Today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “NUCLEAR” can induce worries in patients and society. In this article, base on new documents, we intend to show that this worries has no scientific basis. To produce a realistic view, ...
