| pubmed-article:3335445 | pubmed:abstractText | The transfer of 106Ru in a soil-plant ecosystem was investigated with respect to two chemical forms in compact soil samples under greenhouse conditions with surface and deep-layer contamination. Considerable differences in the uptake of 106Ru were observed between 106RuCl3 and 106Ru-nitrosyl during the first 5-8 wk after the contamination of the soil. The translocation of 106Ru in the soil showed an inhomogeneous distribution of the radioruthenium, with a great part of the total activity remaining in the upper soil layer between 0 and 5 cm even 10 mo after contamination of the soil surface. During the whole experiment, reemission of 106Ru into the air was investigated by using special air collectors under different temperature and light conditions. Although a continuous checking out for a time of about 8 mo, no measurable concentrations of 106Ru could be out for a time of about 8 mo, no measurable concentrations of 106Ru could be found in examined air filters. | lld:pubmed |
