A new report on the United States nuclear weapons testing legacy in the Marshall Islands highlights the lack of studies into important health concerns voiced by Marshallese for decades that make it impossible to have a clear understanding of the impacts of the 67 nuclear weapons tests.

The Legacy of US Nuclear Testing in the Marshall Islands, a report by Dr Arjun Makhijani of the Institute for Energy and Environmental Research, was released late last month.

The report was funded by Greenpeace Germany and is an outgrowth of the organisation’s flagship vessel, Rainbow Warrior III, visiting the Marshall Islands from March to April to recognise the 40th anniversary of the resettlement of the nuclear test-affected population of Rongelap Atoll.

Dr Mahkijani said that among the “many troubling aspects” of the legacy is that the United States had concluded, in 1948, after three tests, that the Marshall Islands was not “a suitable site for atomic experiments” because it did not meet the required meteorological criteria.

“Yet testing went on,” he said.

“Also notable has been the lack of systematic scientific attention to the accounts by many Marshallese of severe malformations and other adverse pregnancy outcomes like stillbirths. This was despite the documented fallout throughout the country and the fact that the potential for fallout to cause major birth defects has been known since the 1950s.”

Dr Makhijani highlights the point that, despite early documentation in the immediate aftermath of the 1954 Bravo hydrogen bomb test and numerous anecdotal reports from Marshallese women about miscarriages and still births, US government medical officials in charge of managing the nuclear test-related medical programme in the Marshall Islands never systematically studied birth anomalies.

Committed billions of dollars
The US Deputy Secretary of State in the Biden-Harris administration, Kurt Cambell, said that Washington, over decades, had committed billions of dollars to the damages and the rebuilding of the Marshall Islands.

“I think we understand that that history carries a heavy burden, and we are doing what we can to support the people in the [Compact of Free Association] states, including the Marshall Islands,” he told reporters at the Pacific Islands Forum leaders’ meeting in Nuku’alofa last year.

“This is not a legacy that we seek to avoid. We have attempted to address it constructively with massive resources and a sustained commitment.”

Among points outlined in the new report:

• Gamma radiation levels at Majuro, the capital of the Marshall Islands, officially considered a “very low exposure” atoll, were tens of times, and up to 300 times, more than background in the immediate aftermaths of the thermonuclear tests in the Castle series at Bikini Atoll in 1954.
• Thyroid doses in the so-called “low exposure atolls” averaged 270 milligray (mGy), 60 percent more than the 50,000 people of Pripyat near Chernobyl who were evacuated (170 mGy) after the 1986 accident there, and roughly double the average thyroid exposures in the most exposed counties in the United States due to testing at the Nevada Test Site.

Despite this, “only a small fraction of the population has been officially recognised as exposed enough for screening and medical attention; even that came with its own downsides, including people being treated as experimental subjects,” the report said.

Women reported adverse outcomes
“In interviews and one 1980s country-wide survey, women have reported many adverse pregnancy outcomes,” said the report.

“They include stillbirths, a baby with part of the skull missing and ‘the brain and the spinal cord fully exposed,’ and a two-headed baby. Many of the babies with major birth defects died shortly after birth.

Fifty years ago 242 men left New Zealand on a mission to Moruroa Atoll in French Polynesia.

The crew of HMNZS Otago, and later the frigate Canterbury, were sent there to protest against French nuclear testing.

Little did they know that the fallout from the mission would continue decades later, with health problems and worries about the effects on their children and future generations.

Prime Minister Norman Kirk farewelled the Otago on 28 June 1973.

Twenty-year-old sailor Tony Cox was on board.

“I was standing on the deck along with a lot of other guys, and Norman Kirk was with the skipper, talking to various members of the crew.

“He said to me, ‘Don’t worry about anything, son. Nothing’s going to happen, but if it does, we will look after you’.”

Witnessed atmospheric test
A month later the Otago witnessed an atmospheric test just over 20 miles away.

The crew initially sheltered below deck.

“As soon as the flash had gone they said we could go up and have a look, so [we went] up the ladder and opened the door and out we went,” Cox said.

“It was a bit disappointing. It wasn’t like the movies. It was almost a straight line to start with, then it started to form into a mushroom. It had a pinky, grey colour to it.”

Fellow Otago crewman Ant Kennedy turned 20 at Moruroa.

“I got married at Honolulu. I didn’t know I was going to be married then. We were on the way to southeast Asia to be part of New Zealand’s deployment there.

“Then we were called back and it was jokingly called Norm’s Mystery Tour.”

Labour government opposed
France started nuclear tests in the Pacific in the 1960s and Kirk’s Labour government was staunchly opposed.

Cabinet Minister Fraser Colman travelled there on the Otago, and transferred to the HMNZS Canterbury when it took over protest duties.

Aboard the Canterbury, Gavin Smith also witnessed a test.

“We were inside a gas-tight citadel for the explosion. We never thought about the consequences of it until much later, and then people started dying and getting crook.

“We realised that the seawater around there was contaminated. The seawater was used on board for washing vegetables. We washed in it, bathed in it.”

The water was desalinated, but that didn’t remove radiation, as Cox recalls.

“The water around us was contaminated. We didn’t know that,” he said.

‘No fish, no seabirds’
“There were no fish there, so that was a waste of time. There were no sea birds anywhere. They were well dead, gone. It was totally different to all the different oceans I’ve been through over the years.”

Kennedy said his health was okay, but he knew he was one of the lucky ones.

He remembers one fellow sailor needing surgery.

“He had this bad cancerous stuff on his face. And a guy called Cloggs. He was a signalman on Canterbury. He was at one of our reunions, and basically he came to that and that was that.

“He was younger than me.

“I thought, holy hell. This seems to be a bit out of the ordinary. You’d expect fit, young sailors to live into their 80s.”

About 20 years ago Cox’s oncologist told him he had a rare form of non-Hodgkin lymphoma.

Excessive doses of radiation
“[He said], ‘The only time you get this type of cancer is from excessive doses of radiation. Where would you have got that from?’

“I said, ‘I did go to a nuclear bomb test,’ and he said, ‘That’ll do it’.”

Veterans’ costs are covered for sickness arising from service.

But as Smith, the president of the Moruroa Nuclear Veterans group, said, there was concern about subsequent generations.

The group, formed in 2013, is active in trying to get recognition for possible effects on their families.

“Our children and grandchildren have oddball illnesses and we would like to know if that was a result of our service at Moruroa,” Smith said.

“Are we passing on bad genes or are we not?

Asking for DNA testing
“All we ask is for DNA testing to be done and when science can prove that fact one way or another we have an answer.

“If science does prove we have passed on bad genes we would simply like our children and grandchildren and the next generations to be looked after if they have an illness that’s related to our service.”

So far, that has not happened, despite regular lobbying of officials and ministers.

For Donna Weir, whose father Allan Hamilton was aboard the Canterbury, that concern was real.

Hamilton died in 2021 from aggressive cancer.

“I have had fertility problems, multiple miscarriages and things like that. We have kids who have problems that nobody can explain, if that makes sense.”

That included stomach and vision problems.

So much trouble
Weir said one older sister, who was conceived before 1973, had no such trouble.

The nuclear test veterans deserved greater recognition for their service, she said.

“They’re some of New Zealand’s most forgotten heroes, I think.

“I asked Dad if he knew then what we now know, would you have gone. His answer was quite simply, ‘I signed up to serve my country and that’s what I did.’”

French nuclear tests in the Pacific went underground from 1974, but continued until 1996. France conducted a total of 193 nuclear tests at Moruroa and Fangataufa atolls in the Pacific, 41 of them atmospheric.

Veterans’ Affairs has been approached for comment.
