FORGOTTEN FALLOUT FROM THE 1954
BRAVO H-BOMB SCREW UP

Contamination of Daigo Fukuryu maru (Lucky Dragon V) From U.S. Thermonuclar Test Was Partial Inspiration
for Godzilla Film

As we contemplate the effects of Japan's instant hall of triple disaster (earthquake, tsunami, nuke), it might be useful to recall another unknown nuclear event of the past. In March 1954, during test of our new H-nuke Bravo in the Marshall Islands, a fishing vessel (the ironically named Daigo Fukuryu maru aka Lucky Dragon V) sailed unawares into the fallout patterns of the bomb. The bomb was equivalent to 17 megatons of TNT, 1,300 times the destructive force of the bomb dropped on Hiroshima, and was specifically designed to create a vast amount of lethal fallout. Although barely mentioned in the U.S., the incident opened the still raw wounds of Hiroshima/Nagazaki, affected the global tuna supply and was a partial inspiration for the Godzilla film released later in the year.

The ship was operating about 85 miles to the west of ground zero. Earlier that year, US authorities had issued a somewhat casual warning defining a danger zone around Bikini, but no specific information had been given regarding the timing or location of the various tests. The Lucky Dragon was operating well outside the prohibited zone, but the Bomb was far more powerful than previously described. (Also, the wind had shifted - just ask the Marshall Islanders).

Having collected the radioactive ash on deck as ill-advised atomic souveniers, Most of the crew suffered the effects of radiation poisoning, but didn't associate the symptoms with the extra sun in the sky. They did not report the incident on the radio.

U.S. Donates $2,800 to Crew Member's Widow
Back in Japan, the condition of the crew members and the circumstances of their injuries became matters of worldwide interest (with very little coverage in the U.S.) and intense concern in Japan. Several of the members suffered the effects of radiation poisoning to some degree, but only Kuboyama Aikichi, the radio telegraph operator, died on September 1954.

The United State donated 1 million yen ( US $ 2,800 ) to the widowand each surviving crew member got an average of $5,000 plus medical expenses. However, most of the U.S. reparations went to pay for damage to the tuna industry (next panel).
Radioative Tuna
Meanwhile, a professor at Tokyo University discovered that fish from the ship were highly radioctive. News of the situation caused a panic and an immediate freeze on fish purchases in the city. The professor requested information from the U.S. Atomic Energy Commission, but his cable was never transmitted by the chief of the Tokyo wire service on the grounds that it was alarmist. Weeks later, Senator Pastore, a member of the joint Congressional Committee on Atomic Energy, returned the United State and issued an optimistic opinion on the fishermen's health. He was another in a long line of Senator's with extensive scientific training, a tradition that has culminated today with Senator James Inhofe of Oklahmoma.

Under pressure from Japan, the U.S. enlarged the danger zone in the nuke proving grounds, which encompassed major Japanese fishing areas. All boats fishing in this area, or taking passage through it, were required to put in at five designated ports and be inspected for radioactivity.

Consumer hysteria increased as 750 tons of tuna were stored in warehouses. The Misaki fish market was closed, precipitating a panic among the fish dealers. The hysteria spread to nearby Yokohama and then to Tokyo itself. The great Tokyo Central Wholesale Market closed for the first time since the cholera epidemic of 1935. None of these measures worked well. When it became known that fish had been banned from the Emperor's diet, people became even more worried. Prices plummeted to still lower depths and some fish dealers were forced into bankruptcy.

Ambassador John M. Allison sought to take some of the sting out of the criticisms by issuing a press release on March 19, in which he said theat he was "authorized to make clear that the Unites States is prepared to take such steps as may be necessary to insure fair and just compensation if the facts so warrant."

A US congressman, Melvin Price from Illinois (predecessor of John Shimkus), commented that the presence of the Japanese fishing boat so close to the blast indicated that a Soviet submarine could have come even closer. At this point, Representative W. Sterling Cole, chairman of the Joint Atomic Committee, was interpreted in the Japanese press as suggesting that the Lucky Dragon may have been on a spying mission. This suggestion infuriated the Japanese.

Although the Lucky Dragon incident did make the front pages of U.S. papers on St. Patricks Day 1954, the radioative tuna issue did not seem to resonate with the editors. The AEC (charged with both regulating and promoting atomic energy) released the following statement: "The opinion of the American Energy Commission scientific staff based on long-term studies of fish in the presence of radioactivity is that there is negligible hazard, if any, in the consumption of fish caught in the Pacific Ocean outside the immediate test area subsequent to tests....Any radioactivity collected in the test area would become harmless within a few miles....and completely undetectable within 500 miles or less...."

Dispite the AEC's assurannces, on March 27 the Koei Maru ( Radiant Glory) put into the port of Mastic with thirty-seven tons of tuna, which was found to be radioactive above the level established by the Ministry of Health and Welfare. Meanwhile (this is good), American fish dealers indicated that Japanese standards for radiation WERE NOT RIGID enough and began rejecting fish that was even slightly contaminated. West Coats tuna canneries were alerted to the radioactivity problem. Records of the food and Drug Administration show that two radioactive fish were picked up at one cannery. No details other than that the " radioactivity was insignificant" are available, but it is known that secret meeting took place between representatives of tuna industry, the Food and Drug Administration, the Atomic Energy Commission, and the State Department. An acceptable level of radioactivity was agreed upon at this meeting but the level was classified as "confidential" and not released to the public. Ever.
