On March 10th 2023, a cylinder containing caesium-137 was found missing from power plant near Bangkok, Thailand. This generated lots of fear and anxiety, fuelled by social media inadequate statements the authorities. Later it discovered in foundry, compressed partially melted. It is clear this incident that risk communication inadequate. Two case studies Southeast Asia, 2004 Asian Earthquake Ts...

The present work investigates an appropriate way to calculate the 1700 atomic density changes in the reactor operations. To automate this procedure, a computer program has been designed by C#. This program suggests a way to solve this problem which is based on the solution system of differential equations (Bitman) that it is designed according to Runge-Kutta Fehlberg method. The designed softwa...

Permanent implant of sealed radioactive sources is an effective technique for treating cancer. Typically, the radioactive sources are implanted in and near the disease, depositing radiation absorbed dose locally over several months. There may be instances where these patients must undergo unrelated surgical procedures when the radioactive material remains active enough to pose risks. This work ...

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...

Non-selective luminescence spectroscopy and luminescence line-narrowing spectroscopy were used to study the retention of UO2(2+) on titanium dioxide (TiO2), synthetic calcium silicate hydrate (C-S-H) phases and hardened cement paste (HCP). Non-selective luminescence spectra showed strong inhomogeneous line broadening resulting from a strongly disordered UO2(2+) bonding environment. This problem...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

Experts in the US Department of Homeland Security have determined that a possible threat exists for the detonation of Radiological Dispersion Device (RDD) and/or an Improvised Nuclear Device (IND) on US soil. Various US government agencies are currently procuring radiation monitoring systems to attempt to guard our homeland at locations such as border crossings, seaports, airports and post offi...

exchange of radioactive isotopes in the culture medium for non-radioactive isotopes in the roots. The fraction of potassium present in the root capable of rapid exchange for isotopes in the culture medium is calculated. This fraction is believed to be associated with the colloidal phases of the protoplasm and cell wall, and for this reason may have a special significance for the study of certai...
