Doğada yaşayan tüm canlılar sürekli olarak doğal ve yapay radyasyon kaynaklarından yayınlanan iyonlaştırıcı radyasyona maruz kalmaktadır. Bu nedenle, yaşam alanları ziyaret edilen bölgelerde radyoaktivite düzeylerinin belirlenmesi önemlidir. çalışmada, Rize ili İkizdere ilçesine bağlı İkizdere-İspir karayolu üzerinde bulunan Ovit Dağbaşı Gölünden alınan su örneklerinde 226Ra, 232Th 40K konsantr...

The approach taken in the WHO Guidelines for controlling radiological hazards public water supplies has two stages. first is an initial screening gross alpha and beta activity to determine whether concentrations are below levels at which no further action required; if these exceeded, investigation of concentration individual radionuclides comparison with specific guidance levels. Mineral obtain...

A natural radioactivity in thermal water was investigated based on 19 selected waters from Poland. The analysed results show that the radionuclides’ concentrations study vary over a wide range. temperature of varies above 20 °C to 80 °C. are characterised by different mineralisation, chemical compositions, and belong hydrochemical types. There is good correlation between depths aquifer formatio...

Natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in Iran. Spotting such a high risk areas can help reducing the amount of their probable risk. A 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the Caspian Sea. This geotechnical hazard map divides the study area to 15 hazard classes (...
