Environmental radioactivity in Greenland in 1977.

Recent trends of environmental radioactivity in Greenland and the Faroe Islands

Effect of various treatments on toxicity of inhaled vinylidene chloride.

The toxicity of vinylidene chloride (VDC) was studied in mice and rats exposed to various concentrations of the vapors for 23 hr/day. In addition, the ability of various treatments to alter parameters of toxicity was evaluated. Mice were more sensitive than rats both to the acute lethal and hepatotoxic effects of VDC. Disulfiram treatment reduced the acute lethal and hepatotoxic effects of inha...

Characterization of uranium and plutonium containing particles originating from the nuclear weapons accident in Thule, Greenland, 1968.

To improve long-term radioecological impact assessment for the contaminated ecosystem of Bylot Sound, Greenland, U and Pu containing particles have been characterized with respect to particle size, elemental distribution, morphology and oxidation states. Based on scanning electron microscopy with XRMA, particles ranging from about 20 to 40 microm were isolated. XRMA and mu-XRF mapping demonstra...

Natural radioactivity in virgin and agricultural soil and its environmental implications in Sungai Petani, Kedah, Malaysia

A study on natural radioactivity in virgin and agricultural soil samples collected from Sungai Petani was conducted using high-purity germanium. The mean activity concentrations of 226Ra, 232Th, and 40K in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 Bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 Bq kg−1, respectively. The co...
