Code	Database serial number - unique ID	n/a		
Identifier	UIAR unique label - chemical analysis number. Where the number is the same (e.g. 1a, 1b) samples were from the same site			
Date_of_90Sr_measurement	Date of measurement dd-mmm-yy	n/a		
90Sr_exchangeable_form_in_soil_%	Percentage 90Sr present in soil in an exchangeable form	percentage		
Relative_uncertainty_of_90Sr_exchangeable_form_portion_in_soil_%	Relative uncertainty of determination (at 95% confidence interval)	percentage		
85Sr_exchangeable_form_in_soil_%	Percentage 85Sr present in soil in an exchangeable form	percentage		
Relative_uncertainty_of_85Sr_exchangeable_form_portion_in_soil_%	Relative uncertainty of determination (at 95% confidence interval)	percentage		
90Sr_activity_in_the_FP-associated_form_%	Percentage 90Sr present in soil associated with fuel particles	percentage
	May contain negative values; these are the consequence of a low percentage of 90Sr in the exchangeable form and a high associated error. Users of the data should assume these values to be zero.	
Relative_uncertainty_of_90Sr_activity_in_the_FP-associated_form_%	Relative uncertainty of determination (at 95% confidence interval)	percentage
