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...

The design, development and operation of a network for the monitoring of the nonionizing electromagnetic radiation in Greece is presented in this paper. Two independent sub-networks, called “Hermes” and “pedion24” have been operating since November 2002 in several areas, and more than 4,000,000 electric field strength measurements have been conducted to date. The measurement results indicate th...

The synchrotron radiation by the relativistic particles is a useful and important diagnostic tool to obtain various beam parameters. The visible light of the synchrotron radiation emitted in a bending magnet of the BEPC storage ring is reflected through the window by a watercooled mirror in the vacuum chamber and then directed by a remote controlled mirror onto the optical bench supporting the ...

The increasing of procedures using fluoroscopy in interventional cardiology procedures may increase medical and patients to levels of radiation that manifest in unintended outcomes. Such outcomes may include skin injury and cancer. The cardiologists and other staff members in interventional cardiology are usually working close to the area under examination and they receive the dose primarily fr...

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...

To prevent excessive radiation damage to its Silicon Vertex Tracker, the BaBar experiment at SLAC uses a radiation monitoring and protection system that triggers a beam abort whenever radiation levels are anomalously high. The existing system, which employs large area Si PIN diodes as radiation sensors, has become increasingly difficult to operate due to radiation damage. We have studied CVD di...

Presented paper describes the results of the individual doses measurements for ionizing radiation, carried out by the Laboratory of Individual and Environmental Doses Monitoring (PDIS) of the Central Laboratory for Radiological Protection in Warsaw (CLOR) for the medical staff employees in several nuclear medicine (NM) departments across Poland. In total there are48 NM departments in operation ...

This survey focuses on recent developments in the radiation chemistry of purine bases in nucleic acids and related model compounds. Both direct and indirect effects of ionizing radiation are investigated with special emphasis on the structural characterization of the final decomposition products of nucleic acid components. Available assays for monitoring radiation-induced base lesions are criti...
