The assessment of the concentration and distribution of l6 N, derived from 16 O in the
cooling water exposed to neutron irradiation, is essential for ensuring radiation safety during …

In gamma camera and single-photon emission computerized tomography, the collimator
removes most photons. Here, a gamma camera without collimator utilizes a specific …

Accurate localization of radioactive materials is crucial in homeland security and radiological
emergencies. Coded-aperture gamma camera is an interesting solution for such …

Gamma camera is a useful device to monitor various radiation sources in a wide range of
areas at nuclear facility. To localize and identify radiation sources in large area, angular …

The mask parameters of a coded aperture are critical design features when optimizing the
performance of a gamma-ray camera. In this paper, experiments and Monte Carlo …

The purpose of this study is to perform radiation monitoring by acquiring gamma images and
real-time optical images for 99m Tc vial source using charge couple device (CCD) cameras …

Abstract The Korea Atomic Energy Research Institute (KAERI) has been developing
pyroprocessing technology, in which actinides are recovered together with plutonium. There …

A new compact gamma camera was developed to detect and image gamma-emitting
radioactive sources in large area. The gamma camera consists of a tungsten coded-aperture …
