Dear colleagues, I have a project about the plants, in my project I measure the specific activity of the detected radionuclides by gamma spectroscopy, and I need to compare the calculated results with the recommend limits of the specific activates of U-238 , Th-232 ,and K-40 radionuclides of the plants not of the soil or the building materials .
thank you dear Jorge

You can check the International Basic Standards cosponsored by IAEA, WHO, and several other international organizations. You can freely download it from IAEA website at the following link:

You could also check among the ICRP recommendations, which, however, cannot cannot be downloaded free from the www.icrp.org website
Dear Jorge ,
thank you for your time and I wish you a quick recovery .
Check the Radium equivalent activity , annual dose and external hazard index. These 3 are applicable for the limit of the NORM. Refer to UNSCEAR 2000.
I agree with Francesco Bochicchio , you will find it in the IAEA, UNSCEAR and WHO publications.
