It comes just days after radiation readings were found to be double the normal amount in Missouri’s recent snowfall.
According to YouTube user, DutchSinse, who posted a video of him taking the Geiger readings in St Louis, the findings mean that ‘small particles of radioactive material are indeed coming down in the precipitation. Past tests show around 30CPM in the same spot on a nice day with no precipitation’.
He said snowstorms in 2012 also showed alert level radiation readings.
The San Francisco findings prompted federal officials to launch an investigation, according to Infowars.com.
Health officials in San Mateo County confirmed the spike – which was reaching over 150 micro-REM per hour – but said they were ‘befuddled’ about what had caused it.
A video shows a man measuring radiation readings at different spots on the beach south of Pillar Point Harbor.
Background radiation in the areas immediately surrounding the beach are normal, but once the man approaches the water itself, the radiation spikes to at least 500 per cent safe levels and the Geiger counter’s alarm goes off.
The man behind the video claims that on his previous visit to the same beach, radiation readings were 13 times the safe level.
