“…The HPGe measures the γ-rays emitted from the decay of radionuclides. The γ-rays from 41 Ar decays produce a peak in the spectrum at 1293.64 keV whereas the other isotopes commonly produced in the air, such as 11 C, 13 N and 15 O, all produce a positron that annihilates to produce a γ-peak at 511 keV. The HPGe detector also provided an absolute measurement of the 41 Ar activity.…”

Measurements and calculations of the air activation at a high-energy proton accelerator are described. The quantity of radionuclides released outdoors depends on operation scenarios including details of the air exchange inside the facility. To improve the prediction of the air activation levels, the MARS15 Monte Carlo code radionuclide production model was modified to be used for these studies. Measurements were done to benchmark the new model and verify its use in optimization studies for the new DUNE experiment at the Long Baseline Neutrino Facility (LBNF) at Fermilab. The measured production rates for the most important radionuclides -11 C, 13 N,

“…Similarly for the production of 18 F (T 1/2 = 110 min) via the 18 O( p, n) 18 F reaction, the cross section database was extended up to 30 MeV [13], so that large scale production of this radionuclide using medium-sized cyclotrons could be carried out. Furthermore, measurements on the formation of some short-lived positron emitters were extended up to proton energies of about 200 MeV [14]. However, the highenergy data are of more relevance to proton therapy than to radionuclide production.…”

Medical radionuclide / Optimisation of production route / Nuclear reaction cross section / Standardisation of data / Alternative routes for production of 99m Tc and 68 Ga / Non-standard positron emitter / Novel therapeutic radionuclide Summary. Nuclear reaction cross section data are of great significance in optimisation of production routes of radionuclides. This article deals with some newer aspects of data research related to production of both standard and novel radionuclides. The recent work to standardise the known data is discussed and new measurements with regard to further optimisation of production routes of some commonly used radionuclides are mentioned. Attempts to increase the specific activity of some reactor-produced radionuclides through the use of charged-particle induced reactions are outlined. The jeopardy in the supply of 99m Tc via a fission-produced 99 Mo/ 99m Tc generator is considered and its possible direct production at a cyclotron is briefly discussed. Regarding the novel radionuclides, development work is presently focussed on non-standard positron emitters for diagnosis and on low-range highly ionising radiation emitters for internal radiotherapy. Recent nuclear reaction cross section measurements related to the production of the two types of radionuclides are briefly reviewed and some anticipated trends in nuclear data research are considered.
