Officials
reject concerns over 500 percent radiation increase on California
beach
Health
officials in California are now telling residents not to worry after
a video uploaded to the internet last month seemed to show high
levels of radiation at a Pacific Coast beach.

The
video, “Fukushima radiation hits San Francisco,” has been viewed
nearly half-a-million times since being uploaded to YouTube on
Christmas Eve, and its contents have caused concern among residents
who fear that nuclear waste from the March 2011 disaster in Japan may
be arriving on their side of the Pacific Ocean.
Throughout
the course of the seven-minute-long clip, a man tests out his Geiger
counter radiation detector while walking through Pacifica State Beach
outside of San Francisco. At times, the monitor on the machine seems
to show radiation of 150 counts-per-minute, or the equivalent of
around five times what is typically found in that type of
environment.
After the video began to go viral last month, local, state and federal officials began to investigate claims that waste from the Fukushima nuclear plant has washed ashore in California. Only now, though, are authorities saying that they have no reason to believe that conditions along the West Coast are unsafe.
The
Half Moon Bay Review reported on Friday that government officials
conducted tests along California’s Pacific Coast after word of the
video began to spread online, but found no indication that radiation
levels had reached a hazardous point.
“It’s
not something that we feel is an immediate public health concern,”
Dean Peterson, the county environmental health director, told the
Review. “We’re not even close to the point of saying that any of
this is from Fukushima.”
According
to the Review’s Mark Noack, counts-per-minute does indeed measure
radiation, but “does not directly equate to the strength or its
hazard level to humans.” And while the paper has reported that
testing conducted by Peterson’s department on their own Geiger
counters has since revealedradiation level of about 100 micro-REM per
hour, or about five times the normal amount, officials are confident
that there is nothing to be concerned about.
“Although
the radiation levels were clearly higher than is typical, Peterson
emphasized that it was still not unsafe for humans,” Noack wrote.
“A person would need to be exposed to 100 microREMs of radiation
for 50,000 hours before it surpassed safety guidelines by the
Occupational Safety and Health Administration, he explained.”
Even
so, officials are still uncertain as to why those levels — even if
they are relatively safe — seem to be five-times higher than what
is expected. Peterson told the Review he was “befuddled” over the
ordeal, but suggested the culprit could be something not too sinister
— such as red-painted eating utensils buried on the beach.
“I
honestly think the end result of this is that it’s just higher
levels of background radiation,” he said.
Researchers
at the Geiger Counter Bulletin website have since tried to make sense
of the reading on their own, and agree that the levels being detected
are several times over what should be expected. According to a post
on their website from this weekend, however, an independent testing
of soil taken from near Pacifica State Beach tested positive for some
radioactive material — but nothing that would have come from
Fukushima.
The
results of testing conducted by California’s Department of Public
Health are expected to be announced later this week.
