Background. Although radiation exposure is of great concern to expecting patients, little information is available on the fetal radiation dose associated with prophylactic internal iliac artery balloon occlusion (IIABO). Here we estimated the fetal radiation dose associated with prophylactic IIABO in Caesarean section (CS). Cases. We report our experience with the IIABO procedure in three conse...

The main results of the EC project ‘Genomic instability and radiation-induced cancer’ (RADINSTAB) are reviewed and the potential implications of genomic instability and bystander effect for risk assessment and radiation protection discussed. A basic paradigm in radiobiology is that, after exposure to ionising radiation, the deposition of energy in the cell nucleus and the resulting damage to DN...

Pediatric neck masses comprise a wide spectrum of entities, benign and malignant. The role of imaging is to characterize these lesions, in order to better determine which can be expectantly managed and which require immediate intervention. An important consideration in the pediatric population is ionizing radiation; while X-ray and CT can be useful, radiation can have harmful effects, particula...

Although ultraviolet radiation is potentially harmful, it is an important component of terrestrial radiation to which plants have been exposed since invading land. Since then, plants have evolved mechanisms to avoid and repair UV radiation damage. Therefore, it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Most of th...

As a basis for establishing radiation protection standards, a substantial amount of quantitative information is now available on the frequency with which malignant diseases are induced in man by moderately high doses of radiation. Such estimates can now be made not only for irradiation of the whole body but also for exposure of a number of body organs individually. The frequency with which canc...

Antarctic krill, Euphausia superba, is very susceptible to harmful solar radiation because of its unique genetic setup. Exposure occurs in spring to autumn during vertical diel migration and during occasional daytime surface-swarming. We have investigated colour change in Antarctic krill, Euphausia superba, during summer and winter in the Lazarev Sea in response to ultraviolet radiation (UVR) a...

The field of Atmospheric-pressure plasmas has been the focus of many researchers and scientists in the past decade. These specific types of systems are favored because of the few requirements needed for its functioning. Plasmas’ use as a sterilizer is being rapidly explored. Thus, in this process it has become necessary to understand the effect of UV radiation produced during the plasma dischar...

Exposure to ionising radiation as a result of diagnostic imaging is increasing among patients with inflammatory bowel disease (IBD), primarily due to the more widespread use of computed tomography (CT). The potentially harmful effects of ionising radiation are a major cause for concern and radiologists, technologists and referring physicians who have a responsibility to the patient to ensure ju...

this paper presents the current activities on radiation protection in iran. according to the atomic energy organization law of iran the radiological safety is ascribed to the atomic energy organization of iran (a e o i) and the radiation protection department (r p d) is the responsible organ within aeoi. r p d since it's establishment in 1975, with the aim to ensure the protection of man and hi...
