Over the past several years, the Livermore Forensic Science Center has
conducted analyses of nuclear-related samples in conjunction with dom
estic and international criminal investigations. Law enforcement offic
ials have sought conventional and nuclear-forensic analyses of questio
ned specimens that have typically consisted of miscellaneous metal spe
cies or actinide salts. The investigated activities have included nucl
ear smuggling and the proliferation of alleged fissionable materials,
nonradioactive hoaxes such as ''Red Mercury,'' and the interdiction of
illegal laboratories engaged in methamphetamine synthesis.
