background: measurement of background radiation is very important from different points of view especially for human health. the aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( zagros mountains ), chaharmahal and bakhtiari province, in the south west of iran . materials and methods: the outdoors-environmental monitoring exp...

Five different combinations of fluorescent tubes (UV-B/UV-B, UV-B/UV-A, UV-A/ UV-A, UV-B/White, White/White) were used to determine relative effects of UV and visible light on the nucleopolyhedroviruses (NPV) of Helicoverpa zea and Spodoptera exigua. For both viruses, the greatest inactivation occurred with exposure to UV-B radiation. Both virus concentration and radiation exposure time influen...

Radiation burns account for the vast majority of damage by accidental radiation exposure. They are characterized by successive and unpredictable inflammatory bursts that are preceded by a clinically latent postirradiation period. Diagnosis and prognosis of the clinical course of radiation burns have proven to be a difficult task. In a classical clinical setting, no technique can distinguish irr...

Previous studies have shown that physicians tend to underestimate the risks to patients of radiation exposure. This study in 2 Palestinian hospitals aimed to assess physicians' knowledge about the risks associated with the use of radiological examinations. A questionnaire answered by 163 physicians revealed many gaps in knowledge. Only one-third of physicians had received a radiation protection...

Objective(s): The aim of this study was to determine whether high-dose radioactive iodine (Na131I) outpatient treatment of patients with thyroid carcinoma is a pragmatically safe approach, particularly for the safety of caregivers. Methods: A total of 79 patients completed the radiation-safety questionnaires prior to receiving high-dose radioactive iodine treatment. The questionnaire studied th...

although there are substantial experimental, epidemiological and clinical evidences that high doses of ionizing radiation cause cancer and other detrimental biological effects, the health effects of human exposure to chronic low dose radiation exposures are still poorly known. people in some areas around the world live in dwellings with radiation and radon levels as much as more than 200 times ...

Background: Male infertility is defined as an inability to impregnate a fertile female; it is a widespread problem which is usually caused by some male factors such as low quantity and quality of sperm, specifically oligospermia and azoospermia. Objective: This study aimed to evaluate the bio-positive effects of low power density Wi-Fi radiation on the reproductive system of infertile and...

introduction: good functional capacity has a high negative predictive value (npv) in patients with known or suspected coronary artery disease (cad) similar to a normal gated myocardial perfusion imaging (gmpi). aim of this study was to evaluate npv of functional capacity during treadmill exercise in patients with normal gmpi in pakistani population. methods: this was a prospective study which ...

introduction: to measure radiation exposures rate in low-risk patients having stress-only and stress-rest myocardial perfusion imaging. methods: this was a prospective study conducted from january 2012 till november 2012 upon patients with low pre-test probability for coronary artery disease (cad). a stress mpi (stress-only if mpi is normal and no resting study) followed by a resting mpi study...
