Description

Studies were undertaken to determine the plant availability of /sup 134/Cs and /sup 85/Sr amended to Rupert surface soil and an associated subsoil. Concentration ratios for cheatgrass (Bromus tectorum) and tumbleweed (Salsola kali) grown on /sup 134/Cs amended Rupert soil were 0.15 and 0.28, respectively; values for amended subsoils were 0.074 and 0.13, respectively. Rupert surface soil and subsoil amended with /sup 85/Sr gave concentration ratios of 15 and 7, respectively, for both tumbleweed and cheatgrass. While pot size (1 vs 4 kg) had a market effect on concentration ratios, values for greenhouses and growth chamber grown plants were generally … continued below

While pot size (1 vs 4 kg) had a market effect on concentration ratios, values for greenhouses and growth chamber grown plants were generally similar. Aging of both Rupert surface soil and subsoils for 1 to 30 days prior to planting had a pronounced effect on the availability of /sup 134/Cs for uptake by plants, but no effect on /sup 85/Sr uptake.
