The present research was carried out to investigate the behavior of radon ( 222 Rn) concentrations over carbonate and evaporite sequences assess related health hazards. A total 50 points from three different stratigraphic units, namely, Bahadurkhel Salt, Jatta Gypsum, Kohat Formation Eocene age, were analyzed for in district Karak, Khyber Pakhtunkhwa, Pakistan. Measurements levels made by using...

Air-ions and radon are two atmospheric trace constituents which have two opposite effects on human health: the ions are beneficial, and radon gas is potentially lethal as it increases the risk of lung cancer. In the lower troposphere, radon is the most important generator of the air-ions. Ionization by cosmic rays and radioactive minerals is almost constant in daily cycles, and variation of air...

Researchers around the world had already established that radon and thoron are a hazard to the human health. Different techniques and methods are applied in order to measure them as accurately as possible. In Romania, most measurements earlier conducted were focused on using grab-sampling measurements to establish the two gasses decay progeny activity concentration; however, recently, there has...

Coconut water has several uses that are beneficial to humans, mainly because of its nutritional and medicinal properties. In this study coconut samples were collected from the fresh mature coconuts packaged processed measure radon concentrations in them. The results used estimate annual effective radiation dose general adult population ingestion water. analyzed for using Durridge RAD-7 detector...

Thoron 220Rn is one of four naturally occurring radon isotopes. It has a half-life T1/2 equal to 55 s. Radon isotopes are chemically inert radioactive gases that occur in the environment as a result of the decay of radioactive elements in soil and minerals. While radon 222Rn results from the decay chain of uranium 238U, thoron 220Rn results from the decay of thorium 232Th. Both uranium and thor...

Telah dilakukan penelitian tentang penentuan aktivitas spesifik radionuklida alam pada sumber air panas di Nagari Pariangan Sumatera Barat. Tujuan ini untuk mengetahui 222Rn, 226Ra,232Th dan 40K. Penelitian menggunakan sampel yang diambil dari tiga berbeda. Aktivitas diukur dua alat yaitu Durridge Rad7 Radon Detector dengan protokol WAT250 222Rn spektrometer gamma Hasil diperoleh berdasarkan pe...
