Oh now!

Jack -- may your relentless optimism reverse the flow of the roaring river rushing down on us and worm its way into President Trump's mind, distract him from retribution and revenge and the Epstien guest list and mass deportations and his cratering poll numbers...and make him see: I'm a genius! No one knows as much as me about nuclear science! We're gonna have cheap electricity the likes of which we've never seen!

Hey -- could happen! Rock on!

This comment is targeted at those new to the field like me. SNT can be used to describe two different things in the field of radiation harm.

1/ SNT as used by Jack Devanney, and others, refers to Sigmoid No Threshold which has the concept of NO SAFE THRESHOLD but is NON-LINEAR, S-shaped. The method takes account of biological repair mechanisms and differences in how radiation doses are acquired i.e. ranging big blast to small regular doses. See https://jackdevanney.substack.com/p/snt-for-dummies

2/ SNT as used in IAEA and UK nuclear regulatory documents refers to Strict/Safe No Threshold which is an extension of the LINEAR LNT. LNT does not reflect that, in some parts of the world, people receive low levels of natural radiation on a daily basis but remain unharmed after decades of exposure. LNT is described in more detail here: https://jackdevanney.substack.com/p/lnt-is-nonsense

Be aware of this when reading discussions/documents/searches about SNT. I initially found the two versions very confusing!
