A new low background laboratory in Pyhäsalmi mine in the Central Finland has been put into operation in
the beginning of 2017. The laboratory operates at the depth of 1436 m (~4100 meters of water
equivalent). In this paper, we present description of the laboratory’s existing facility and background
conditions. In the laboratory, a series of measurements has been started where the 14C concentration is
determined from several liquid scintillator samples. A dedicated setup has been designed and constructed
with the aim of measuring the 14C/12C ratio smaller than 10-18
.
