Status report on long-time decay measurements of 137Cs radioisotope
The constancy of nuclear decay rates can be investigated via long-duration
precision measurements. It is still an open question whether any (annual)
modulation can be observed. Long-lasting nuclear decay rate measurements have
been the subject of considerable research effort. A decay rate measurement with
a 137Cs source is currently being conducted 30 meters below the ground at the
J\'anossy Underground Research Laboratory (JURLab, Csilleb\'erc, Hungary)
utilizing a High-purity Germanium (HPGe) detector. The laboratory is the
low-radiation-background part of the Vesztergombi High Energy Laboratory (VLAB)
on the KFKI campus, Csilleb\'erc, Hungary. From October 2022 to April 2024,
data of 18 months' worth have been collected, providing a new opportunity to
look for variations in decay rates. The experimental setup, data processing
method, and the first results of this measurement are presented here.
