Determination of Radionuclide Concentration in Human Teeth in Najaf Governorate, Iraq
Introduction: 238U decays with alpha particles emission into 234Th and the series ends with 206Pb. The unstable nucleus loses the energy with emitting ionizing alpha particles for reaching a stable state. It is undergoing alpha decay with decay energy (4.679 MeV). Alpha particles enter the human and animal bodies through inhalation of air or ingestion of contaminated food and water. This study ...
متن کاملMinamata Disease and the Mercury Pollution of the Globe
Minamata Disease was discovered for the first time in the world at Minamata City, Kumamoto Prefecture, Japan, in 1956 (Minamata Disease Research Group; 1968, Harada M; 1995), and for the next time at Niigata City, Niigata Prefecture, Japan, in 1965 (Tsubaki T & Irukayama K; 1977). The both cases were attributed to the methyl mercury that was generated in the process for producing acetaldehyde u...
متن کاملThimerosal as discrimination: vaccine disparity in the UN Minamata Convention on mercury.
When addressing toxins, one unmistakable parallel exists between biology and politics: developing children and developing nations are those most vulnerable to toxic exposures. This disturbing parallel is the subject of this critical review, which examines the use and distribution of the mercury (Hg)-based compound, thimerosal, in vaccines. Developed in 1927, thimerosal is 49.55% Hg by weight an...
متن کاملMigration of mercury from dental amalgam through human teeth.
Exposure to mercury from dental amalgams, with possible negative health effects, has generally been considered to occur via either erosion or evaporation directly from the surface of fillings, followed by ingestion. The aim of this study was to determine the relative importance of the direct migration of mercury through the tooth as an alternative exposure pathway. X-ray fluorescence imaging ha...
متن کاملPreliminary Study on Natural Radionuclide Concentration in Samosir area
Measurement of natural radionuclides concentration in Samosir area of Sumatera island of Indonesia aims to obtain basis data of the content of radionuclides that could be tended in the development of the area. This research was conducted using Neutron Activation Analysis (NAA), which consists of a sampling of soil of Samosir Island as the residential area and the soil surrounding of Pangururan ...
