We developed an analytical method for organically bound 3H (OBT) in biological environmental samples by using noble gas mass spectrometry of 3He produced from 3H. Three environmental samples with background level OBT concentrations were analyzed, and

The formation of non-agglomerated titania particles by oxidation of titanium-tetra-isopropoxide (TTIP) has been studied in a methane/oxygen coflow diffusion-flame reactor. A change in the proportion of virtually non-agglomerated particles in TEM imag

Dolon village, located about 60 km from the border of the Semipalatinsk nuclear test site, is known to be heavily contaminated by the first USSR atomic bomb test in August 1949. Soil samples around Dolon were taken in October 2005 in an attempt to ev

The spent nuclear fuel reprocessing plant in Rokkasho, Japan, has been undergoing final testing since March 2006. During April 2006-October 2008, that spent fuel was cut and chemically processed, the plant discharged (129)I into the atmosphere and co

Little is understood about the usefulness of sulfur isotopic ratios (sigma 34S) in tree rings because the sulfur content in rings is generally insufficient for analysis using conventional methods. We present sigma 34S values of the water-soluble and

The 14C activities and/or a13C values were measured for tree rings, rices, edible oils, flavors, beers, chickens and eggs. The 14C activity in 1999 ranged from 14.4 to 14.8dpm/g.C for those of tree rings and rices. The 14C activities of oils were in

Atmospheric sulfur oxides, participate matter and deposits (wet and dry deposits) were collected from July 1998 to June 1999 at Kyushu Island, Japan. The isotopic composition of sulfur (δ34S) was measured to identify the source of sulfur in the samp

A simple analytical method for environmental14C with a low background liquid scintillation counter was developed. We used a new gelling agent, N-lauroyl-L-glutamic-α,γ-dibutylamide, for the liquid scintillation counting of14C as CaCO3 (gel suspensi
