Summary. The interactions of high-energy protons with matter produce a large variety of radionuclides due to the diversity of the induced nuclear reactions. Some of those isotopes are very rare, exotic, and, in many cases, difficult to produce by complementary methods. Valuable isotopes, interesting for scientific and technological applications, can be extracted from samples stemming from the surroundings or components of a proton accelerator, in particular if the load of the initial particle current is relatively high (esp. in the Megawatt range).Since PSI operates one of the most powerful high-energy proton accelerators world-wide, this facility is best-suited for an R&D program aimed at "harvesting" such isotopes. An initiative called ERAWAST (Exotic Radionuclides from Accelerator Waste for Science and Technology) was started in 2006 in order to identify and motivate potential users. After six years, first achievements as well as realistic future plans for front-end experiments are available.The present contribution describes radiochemical separation techniques for selected examples, summarizes the most prominent results and gives an outlook on the upcoming experiments within the scope of the ERAWAST program.

“…Normalization has been performed against NIST SRM 4325 with the certified value of ( 10 Be/ 9 Be) = (2.68 ± 0.14)x10 À11 and the ASTER in-house standard SM-Al-11 with ( 26 Al/ 27 Al) = (7.401 ± 0.064) Â 10 À12 , which has been crosscalibrated against the primary standards certified by a round-robin exercise [15].…”

“…Since the acceptance tests of the French 5 MV accelerator mass spectrometry facility ASTER in 2007, routine measurement conditions for the long-lived radionuclides 10 Be and 26 Al have been established. Yearly sample throughput as high as over 3300 unknowns has been reached for 10 Be in 2010.…”

“…Yearly sample throughput as high as over 3300 unknowns has been reached for 10 Be in 2010. Cross-contamination for volatile elements has been largely solved by an ion source upgrade allowing 36 Cl measurements at ASTER.…”

“…Besides time dependent mass fractionation, another likely reason for this effect might be source memory, thus, asking for sophisticated measurement strategies and improved data evaluation and eventually further ion source improvement. Finally, after establishing quality assurance by cross-calibration of secondary in-house 26 Al and 41 Ca standards and taking part in round-robin exercises of 10 Be and 36 Cl, a two-step cross-calibration of secondary in-house 129 I standards has been performed. The NIST 3231 standard containing 129 I/ 127 I at (0.981 ± 0.012) Â 10 À6 has been used for step-wise dilution with NaI to produce gram-quantities of lower-level standards for every-day use.…”
