Sažetak
Lead is the principal soldering material in computer chip manufacturing today. However, commercially available lead is contaminated by the radioactive radon and its daughters ; some of them have a considerably energy (>5 MeV)sufficient enough to induce the computer chip "soft error". Since the computer chips are getting smaller and smaller, such "soft errors" occure more and more often. Therefore, it is absolutely necessary to have a workable metrology for measuring the rare events of radon family radioactive chain decay to assess accurately the risk of error for such sophisticated systems like IBM, deep space probes, and Homeland Security.
