Use of Radioactive Samples

ESRF procedures for experiments using radioactive samples on beamlines other than beamline BM20 (ROBL)

Summary of important deadlines and time constraints

• All detailed information concerning the samples and the experimental set-up must be provided to the ESRF as soon as possible, normally one month before the experiment starts.
  If two weeks before the starting date all the required information is not available, the experiment will be cancelled (see § 4).

• Users bringing radioactive samples with them to the ESRF must arrive on weekdays, between 08h00 and 16h00 (see § 7.1).

• During the experiment, the transfer of samples between the Radioactive Samples Laboratory and the beamline is only possible on working days, between 08h30 and 16h00 (see §§ 3.2 and 3.3).

• At the end of the experiment, at least one of the users must remain at the ESRF until all samples have been returned to and verified by the ESRF Radiation Protection Group.  Note that samples can only be returned to the ESRF Radiation Protection Group during working days, between 08h30 and 16h00 (see § 6).
