Background: The equivalent dose in the human body due to the natural gamma-emitting radionucides (238U, 232Th and 40K) in the surface soil surrounding the Consolidated Tin mine site in Bukuru-Jos, Nigeria has been determined in this study. Materials and Methods: Measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (Canberra Series 10 plus) coupled ...

Thirty-one samples of cigarettes have been collected from local markets of different types of origins. The samples were selected according to a survey distributed to smokers by paper and digital survey to see the most heavily traded among smokers and in addition to a number of questions to see how the awareness and the culture of smokers in diseases caused by smoking and considered this study t...

Among radiation exposure pathways to human beings, inhalation dose is the most prominent one. Radon, thoron, and their progeny contribute more than 50 per cent to the annual effective dose due to natural radioactivity. South west coast of India is classified as a High Natural Background Radioactivity Area and large scale data on natural radioactivity and dosimetry are available from these coast...

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...
