Introduction: Nuclear moisture density gauges are widely used in construction industry in different countries across the world, including Ghana, on a large scale. Like all irradiating devices, the nuclear gauges should be subjected to radiation safety assessment based on radiation protection and safety principles. Regarding this, the objective of this research was to i...
Background: The aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at Bahawalpur Institute of Nuclear Medicine and Oncology department. Materials and Methods: Annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to Radiation Dosimetry Laboratory (RDL), Pakistan Institute of Nuc...
Nuclear power is a sustainable energy source, but radiation management required for its safe use. Radiation-detection technology has been developed the of radioactive materials in nuclear facilities performance may vary depending on size and complexity structure facilities. In this study, monitoring system using multi-sensor network was designed to monitor large facility. Additionally, an artif...
Detection of landmines using nuclear techniques has been studied extensively since the late 1940s. Nuclear techniques look at either a return radiation, which is characteristic of explosive components that are infrequently found in soil (e.g., nitrogen or carbon), or an intensity change of a noncharacteristic scattered radiation, which is a function of a parameter that differs between soil and ...
Halide perovskites have been considered as nuclear radiation detection materials due to their high mobility, long carrier lifetime, and absorption coefficient. However, it has reported th...
Background and purpose: In recent years the use of radioactive materials for diagnostic and therapeutic purposes grew rapidly in nuclear medicine. The imaging technicians and nursing staff in radiopharmaceutical centers are in close contact with patients. Therefore, they are exposed to different radiation levels. This study was done on risk assessment of staff exposed to 99mTc-MIBI Materials...
background: various variance reduction techniques such as forced detection (fd) have been implemented in monte carlo (mc) simulation of nuclear medicine in an effort to decrease the simulation time while keeping accuracy. however most of these techniques still result in very long mc simulation times for being implemented into routine use. materials and methods: convolution-based forced detectio...
Methods of detecting and locating nuclear radioactive targets via wireless sensor networks (WSN) are proposed in this paper. In real applications, a nuclear radioactive target can be interpreted either as a hidden nuclear weapon held by nuclear terrorists or as a leak of nuclear radioactive materials at a unit of nuclear power stations. Assume a WSN is composed of radiation detectors deployed ...
