What is the non governement standard/target going to be set at? Do private companies need to adhere to the 'new' NASA limit?

Regulations will appear. There are already regulations about radiation exposure that will be immediately extended into space travel if no regulatory body acts quickly enough.

A short search gave me this number, apparently for the US:

> 20 mSv a year, averaged over defined periods of 5 years with no single year >50 mSv

This basically prohibits paid-for space labor.

Surely in such unusual circumstances any limits must be set as part of a cost benefit analysis from the point of view of the person concerned. One person might be rationally willing to risk higher exposure in the pursuit of knowledge.
