I have compiled a short list i had already im my files:

at first: Check the internet for Presentation,Lectures, Papers of Uwe Ewert and Uwe Zscherpel from BAM, already here in NDT.net you find a lot. also check Researchgate.net (https://www.researchgate.net/profile/Uwe_Ewert2 , https://www.researchgate.net/profile/Uwe_Zscherpel ) . Even videos can be found – e.g.: https://www.youtube.com/watch?v=xefUp80WSfc
BAM is a leading Institute in this field as they work also as a leading body in standardisation e.g. they do contribute to the ASTM Standards – see here
https://www.astm.org/search/fullsite-search.html?query=digital%20radiography&

one book from ASTN regarding DR – an older version is linked here (legal?)
ASNT_Level_III_Study_Guide_Radiographic – you get from ACADEMIA (https://www.academia.edu/38830479/ASNT_Level_III_Study_Guide_Radiographic_Testing_Method)
also this book:
Handbook of Nondestructive Evaluation -Charles J.Hellier – you get from ACADEMIA https://www.academia.edu/35003120/HANDBOOF_OF_NONDESTRUCTIVE_EVALUATION

The IAEA has a lot of valuable documents:
IAEA( https://www.iaea.org/publications ) – check this page about radiography publications, there are some publications nemed

In canada I found this some times ago:
Examination Guide forInitial Certification, Industrial Radiography, Aerospace Sector http://publications.gc.ca/collections/collection_2018/rncan-nrcan/M39-140-2002-eng.pdf
http://publications.gc.ca/collections/collection_2017/rncan-nrcan/M39-136-2002-eng.pdf
