A suggested revision to the specific activity limit for tritiated water transported as LSA-II

Abstract

Tritiated water of specific activity not greater than 0.8 TBq L⁻¹ is classified as LSA-II. This paper demonstrates by some simple calculations that the dose that may result from an accident involving tritiated water of this specific activity is very low and suggests that even if the specific activity limit of tritiated water which may be transported as LSA-II is raised above 0.8 TBq kg⁻¹, the resulting dose in accident conditions would not be unacceptable.
