LIFE: a sustainable solution for developing safe, clean fusion power.

abstract：:Following a large-scale radiation emergency, affected populations will need to be screened soon after for potential contamination (external or internal). Effective management of the available resources can help maximize the screening throughputs. This paper reports the modeling results for screening throughputs in a p...
