Abstract.
For the first time ancient Roman lead was used to grow a crystal of PbWO4 , and this crystal has subsequently been used as a cryogenic particle detector. The new device provides independent readout of heat and scintillation light and is able to discriminate between \( \beta/\gamma\) interactions and alpha interactions down to few keV. Stringent limits on the \( \alpha\) decays of the lead isotopes are presented. In particular a limit of \( T_{1/2}>1.4\cdot 10^{20}\) y at a 90% C.L. was evaluated for the \( \alpha\) decay of 204Pb to 200Hg .
