In 2008, the UK broadcasting regulator Ofcom issued strong warnings to broadcasters for transmitting Popoff's material, which the regulator felt promoted his products "in such a way as to target potential susceptible and vulnerable viewers". These programs included offers of free "Miracle Manna" that allegedly provided health and financial miracles. In 2009, Popoff began running advertisements in UK periodicals offering a free cross containing "blessed water" and "holy sand". The water, he claimed, was drawn from a spring near Chernobyl (site of the 1986 nuclear reactor disaster). Animals and humans drinking from the spring were purportedly spared radiation sickness. Responders to the ad received a small wooden cross bearing the inscription "Jerusalem" and a solicitation for donations, followed by numerous additional solicitation letters.
