"Nuclear radiation is forever," she added. It doesn't dissipate or disappear. Jeff Patterson, former Physicians for Social Responsibility president said, "There is no safe level of radionuclide exposure, whether from food, water or other sources. Period." In 1953, Nobel laureate George Wald agreed saying "no amount of radiation is safe. Every dose is an overdose."
On March 19, Ralph Nader's "Nuclear Nightmare" article said:
"Over 40 years ago....the Atomic Energy Commission (now the Nuclear Regulatory Commission) estimated that a full nuclear meltdown could contaminate an area 'the size of Pennsylvania' and cause massive casualties."
In square miles, Pennsylvania is one-third the size of Japan. Nader said that "people in northern Japan may lose their land, homes, relatives, and friends as a result of a dangerous technology designed simply to boil water."
On March 25, New York Times writers Hiroko Tabuchi, Keith Bradsher and David Jolly headlined, "Japan Encourages a Wider Evacuation from Reactor Area," saying:
"New signs emerged Friday that parts of the crippled Fukushima Daiichi nuclear plant were so damaged and contaminated that it would be even harder to bring the plant under control soon."
Japan's Nuclear and Industrial Safety Agency (NISA) measured seawater showing "the level of iodine-131 at 50 becquerels per cubic centimeter - 1,250 times the legal limit."
Moreover, several workers were contaminated by water measuring 10,000 times above normal, according to the National Institute of Radiological Sciences. In addition, a senior nuclear executive said "a long vertical crack" running down the side of the reactor vessel (expected to enlarge) was detected "leaking fluids and gases." The Times said, "There is a definite crack in the vessel - it's up and down and it's large. The problem with cracks is they do not get smaller."
