The Validity of Linear Non-Threshold (LNT) Model and its Impact on Derivation of Exposure Limits

Winner - 2023 AIOH Conference 3M Best Paper Award.

This paper discusses the controversy over the use of the linear non-threshold (LNT) model and presents the case for the existence of a threshold of effect for both asbestos and crystalline silica. The existence of threshold affect does not support the suggested need to further reduce the current OELs for these substances and others.
