Radioactive iodine and radioactive cesium: two important radio-hazard elements in post nuclear power plant crisis

The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...

Flooding in Thailand and the problem of radioactive elements leakage

Sir, the big flooding in Thailand in 2011 is one of the problematic flooding in Asia. It causes several destroying to many things in the disaster areas. An important concern is on the effect on the setting with the radioactive elements usage. In Thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. Luckily, ...

Radioactive analysis and radiological hazards of sand in Weifang, China

Background: The activity concentrations of 226Ra, 232Th and 40K in sand used as building material in Weifang of China were investigated for evaluating the radiation hazard. Materials and Methods: Sand samples were collected from Weifang and their radioactivity levels were measured using gamma-ray spectrometry. The radiation hazard for residents was assessed by radium equivalent activity (Raeq),...
