Measurement of Uranium, Radium and Radon Concentration in Ground Water Sampled over Hiroshima Prefecture, Japan

Measurement of radon concentration, and uranium concentration in drinking water in Kirkuk governorate

Dose assessment and measurement of radon concentration in water supplies of Borujerd County in Iran

Background: Radon as a potential risk of radiation exposure is a natural radioactive element that can emit from rocks and soils. Due to solubility in water, it can be inhaled or consumed by the public. The purpose of this study was carrying out measurement and evaluation of radon concentration in samples of drinking water which are collected from water supplies of Borujerd. Materials and Method...

Assessment of radon-222 and radium-226 radioactivity concentration in the mineral and drinking water of Sareyn city

The main objective of this research is measurement and assessment of the Radon-222 and Radium-226 radioactive levels in mineral water and drinking water in the Sareyn city. The guidelines used for Radon-222 and Radium-226 radiation sampling and analysis were ASTM D: 5072-09 and ISO 13165-1: 2013, respectively. The concentration of Radon-222 and radium-226 in mineral water and drinking water sam...

Uranium, Radium, and Radon in Well Water in South Carolina: Distribution and Problems

South Carolina, despite being a small state, possesses a wide range and diversity of hydrogeologic conditions, generally arranged into geologic belts or physiographic provinces. These distinct areas range from the mountains and piedmont with crystalline metamorphic and igneous rocks with major geologic structural features, to a broad coastal plain with sand and limestone aquifers (Fig. 1). Acco...

Highly Toxic Ribbon Worm Cephalothrix simula Containing Tetrodotoxin in Hiroshima Bay, Hiroshima Prefecture, Japan

In 1998, during a toxicological surveillance of various marine fouling organisms in Hiroshima Bay, Japan, specimens of the ribbon worm, Cephalothrix simula (Nemertea: Palaeonemertea) were found. These ribbon worms contained toxins with extremely strong paralytic activity. The maximum toxicity in terms of tetrodotoxin (TTX) was 25,590 mouse units (MU) per gram for the whole worm throughout the m...
