Within the BIOPROTA international cooperation framework, Laura Limer and Graham Smith are involved in the chlorine-36 working group, playing a key role in the group's recent study: Investigation of Cl-36 Behaviour in Soils and Uptake into Crops.
The objectives of the study were to compare the scientific basis supporting alternative approaches used to assess the contamination of soil by Cl-36 and its uptake by crops, and to make relevant illustrative calculations using models based on possibly alternative assumptions (the figure shows the effect of parameter uncertainty on the predicted concentration of Cl-36 in cereal at harvest for an inland site).
