Patients receiving diagnostic doses of radiopharmaceuticals become a source of contamination and exposure for those who come in contact with them, such as nuclear medicine technologists, relatives and nurses. Therefore, the measurement of external radiation dose from these patients is necessary. In this study, the dose rates at distances of 10, 50 and 100cm from 70 patients who received d...

This paper overviews certain radiation detection, perception, and planning challenges for nuclearized robotics that aim to support the waste management and decommissioning mission. To enable the autonomous monitoring, inspection and multi–modal characterization of nuclear sites, we discuss important problems relevant to the tasks of navigation in degraded visual environments, localizability–awa...

Weapons-grade uranium and plutonium could be used as nuclear explosives with extreme destructive potential. The problem of their detection, especially in standard cargo containers during transit, has been described as "searching for a needle in a haystack" because of the inherently low rate of spontaneous emission of characteristic penetrating radiation and the ease of its shielding. Currently,...

Currently deployed passive gamma and neutron detectors screen for illicit nuclear material. Archived data can help evaluate special nuclear material detection probabilities and investigate several related issues, including (1) nuisance gamma alarms arising from naturally occurring radiation, (2) the impact of drifting neutron and gamma background rates, and (3) radioisotope identification perfo...

during the past years, special emphasis was put on medical preparedness in the event of radiological or nuclear emergencies. novin medical radiation institute (nmri) encouraged and supported the national authorities to enhance their cooperation in improving medical response to radiation accident. nmri in cooperation with international atomic energy agency (iaea) and atomic energy organization o...

Radiation-induced cavitation or nucleation for liquids in metastable states allows one to utilize this phenomenon for nuclear particle detection. Indeed, Glaser (1958) received the Nobel Prize for his work on the bubble chamber wherein bubbles are formed in a thermally superheated liquid when nuclear particles strike the metastable fluid. This realization has resulted in the development of so-c...

background: ct scan and nuclear medicine exams deliver a great part of medical exposures. this study examined professional radiation hazards in ct scan and nuclear medicine workers.   methods : in a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. physical dosimetry was performed for exposed workers. blood samples were ob...

Background: Diazinon is one of the most common pesticides in the world playing a similar role to radiation and it could cause DNA breaks and genetic effects.Objective: In this study, radiosensitivity of a lymphoblastic cell line pretreated by Diazinon was investigated. Material and Methods: In this case-control study, the human lymphoblastic T-cell line was divided into 6 groups bas...
