We use a nuclear technique based on the determination of detection efficiencies solid state track detectors CR-39 and LR-115 type II (SSNTDs) for alpha particles emitted from series uranium-238 thorium-232 in phytotherapeutic sample measurement densities registered these to assess activities due uranium-238; thorium-232; radon thoron samples preparations consumed by Moroccan adult patients. For...

This report describes the first stage in solving the structure from motion problem, which is to detect feature points and track them from frame to frame. A number of detectors from the literature, as well as some specially developed detectors, are assessed using a fly-over sequence of Parafield control tower. It is found by this measure that the Harris detector is the best of the conventional d...

Introduction: Protein-protein interaction is one of the most important subjects in molecular biology [1]. Bioassays have been developed to detect and quantify the biomolecular interactions with high sensitivity. There are two general categories of techniques: labelling with compounds and direct molecule identification. Label-free biosensor technologies are among the latter, which are desirable ...

Solid State Nuclear Track Detectors (SSNTD) have been used as passive dosimeters for many decades. Fast neutron detection is performed by detecting recoil protons generated in a hydrogenous material (neutron converter). The dose estimated multiplying the track-spots density present on detector surface calibration coefficient obtained from reference irradiations. Therefore, one needs to automati...

Extensive export quality reserves of granite, dolerite and marbles which are used for interior decorations as wall facing, paving floors, kitchen counter tops, etc., are available in Azad Kashmir. Since these stones contain radium in trace amounts, therefore, its use as a building material may be a potential source of indoor radon. In order to assess health hazards due to the use of these stone...

The FT (peak bolometric photon flux) vs. Ep (peak energy) plane is a powerful tool to compare the burst populations detected by different detectors. Detector sensitivity curves in this plane demonstrate which burst populations the detectors will detect. For example, future CZT-based detectors will show the largest increase in sensitivity for soft bursts, and will be particularly wellsuited to s...

A minimally perturbing plastic scintillation detector has been developed for the dosimetry of high-energy beams in radiotherapy. The detector system consists of two identical parallel sets of radiation-resistant optical fibre bundles, each connected to independent photomultiplier tubes (PMTs). One fibre bundle is connected to a miniature water equivalent plastic scintillator and so scintillatio...
