Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine
The beta decay of 151Sm was measured by means of a metallic magnetic calorimeter. The measurement and subsequent analysis yielded a beta spectrum with an outstanding high-energy resolution of about 70 eV (FWHM) at 22 keV and a very low energy threshold well below 400 eV. The spectrum exhibited unexpectedly elevated beta emission probabilities at ve...

This work aims to develop a practical solution to measure the density of a liquid. Two purposes of this study: (1) using a low-activity source to measure the density of a liquid, and (2) simplifying the experimental arrangement to reduce the size and weight of the measuring system. The proposed solution is to develop a measurement technique without...

A 3.81 × 3.81 cm LaBr3(Ce) detector based portable measurement setup has been developed for in situ gamma spectrometric survey of a contaminated site. This system is suitable for above- and below ground surface gamma spectrometric measurements of 137Cs. However, the minimum detectable activity concentration (MDAC), an important parameter of a measu...

A 30 MeV, 5-10 kW beam power electron linac is under development at SAMEER for radio-isotope production. An enriched 100Mo target will be irradiated to produce 99Mo which will be eluted to give 99mTc. Two approaches of 100Mo target irradiation -converter and direct are studied using GEANT4 simulations. The main aim of this study is to optimize the ...

Thehuman internal dosimetry of the radionuclidic impurities of samarium-153 in a new bone-seeking radiopharmaceutical, 153Sm-1,4,7,10tetraazacyclododecanetetramethylenephosponic acid (153Sm-DOTMP), has been estimated from preclinical data. The effective dose from the impurities in lower-specific-activity 153Sm is less than 17% of the effective dose...

Software, "SyrPIGE", has been developed to perform particle induced γ-ray emission (PIGE) data analysis of thick targets relying on a standard-based method. It allows self-consistent and direct analysis of PIGE data considering easy calibration of PIGE spectra, on-screen identification of every γ-ray line, manual input or evaluation of E12 values f...

The potential of the pyroelectric crystal surface has been estimated using experimental data. The temperature of the pyroelectric crystal, the electron current from the crystal surface to the target, and the X-ray spectrum were simultaneously measured. The potential calculated from the temperature and the electron current was compared with the expe...

Zirconia was investigated as a radiation-resistant support for radium and actinium aqueous ion separations. Acetate and total metal ion concentrations were experimentally evaluated as factors that could affect retention using La and Ba surrogates. Pseudo-second order rate constants were derived and the uptake of La was determined to be endothermic....

The possible damaging effects on human health of inhaled radon and its decay products are of interest to workers and the public. In particular, radon in thermal environments often occurs in high concentrations. Therefore, investigations and remedial actions are important to reduce activity concentration values and associated risk. This work concern...

During the production of oil and gas, barium sulfate (BaSO4) scale occurs on the inner walls of the tubes leading the reduction of the internal diameter, making the fluid passage difficult and complicating the calculation of volume fractions of fluids. In this sense, this study presents a methodology for the development of volume fractions of fluid...
