Production of < sup > 129m < /sup > Xe and < sup > 131m < /sup > Xe via neutron activation of < sup > 128 < /sup > Xe and < sup > 130 < /sup > Xe at ILL-RHF and NCBJ-MARIA high-flux reactors

We describe the experimental setups and procedures used to prepare the stable xenon samples, to open the irradiated samples, and to transfer xenon isomers into reusable transport vials. The activity of 129mXe and 131mXe was measured to be in the range of tens of MBq per sample of 0.8(1)mg, and was proportional to thermal neutron flux density. A small activity of unstable contaminants was also visible in the samples, but their level is not limiting for the GAMMA-MRI project's objectives. In addition, the minimum thermal neutron flux density required to produce 129mXe and 131mXe sufficient for the project could be also determined.PMID:38217938 | DOI:10.1016/j.apradiso.2024.111174
