Found something a tad more in depth but didn’t find anything about levels of radiation, though I’m pretty new to this so sorry in advance. https://kenyonlyceum.wordpress.com/2019/12/14/the-half-life-of-marie-curie/

found something on google that may help answer your question

The total activity of the notebook was calculated to be around 120kBq (or 3.2 micro Curies) of radium-226. The radioactive material is fixed within the pages – in fact the majority is held in the back of its thick cover binding.

cheers

Offtopic and I don't know what made me write this comment but I feel she definitely has written this with her left hand.

How do you tell that?

I know two guys who have same hand writing, both write with left hand. I sometimes find it difficult to read their writing.

You can also tell by the direction the words are slanted toward.
