The activities regulations § 59a

§ 59a Analysis of radioactivity in formation water

If, in connection with the testing of new discoveries, available samples of the formation water are available, these water samples shall be analyzed for the content of naturally occurring radioactive substances. If samples of the formation water are not taken, samples of produced water must be taken for the analysis of the content of naturally occurring radioactive substances as soon as possible after produced water from the field is available.
Section last changed: 01 January 2018

The results of the radioactivity analyses shall form the basis for assessments in the impact assessment in a future development of the discovery, and later for an application for the discharge of naturally occurring radioactive substances from the field.
