Transfer factor of Cs and Sr to various crops in semi-arid environment.

This study focuses on evaluating the transfer factor (F) of Cs and Sr from two basic soil types in the country, i.e. Aridisol and Inceptisol, to 18 common crops belong to six groups, i.

Ageing impact on the transfer factor of Cs and Sr to lettuce and winter wheat.

The study focuses on long-term (extending from 1 to 10 years) lysimeter experiments of the transfer factor of Cs and Sr to lettuce and winter wheat crops. Transfer factors (Fs) were the ratio of the activity concentrations of the radionuclides in crops to those in soil, both as dry weight (Bq kg). Fs of Cs to lettuce decreased significantly with ageing; geometric means for the 1, 2 and 10 year contaminated soil were 0.

Transfer factor of (90)Sr and (137)Cs to lettuce and winter wheat at different growth stage applications.

The effect of clay soil contamination time on the transfer factors (Fvs) of (137)Cs and (90)Sr was investigated in four different growth stages of winter wheat and lettuce crops. The experiment was performed in an open field using lysimeters. The Fvs were the ratio of the activity concentrations of the radionuclides in crops to those in soil, both as dry weight (Bq kg(-1)).

Radiological impacts of phosphogypsum.

This study was carried out to assess the radiological impact of Syrian phosphogypsum (PG) piles in the compartments of the surrounding ecosystem. Estimating the distribution of naturally occurring radionuclides (i.e.
