Reaffirm Commitment to Ban Nuclear Tests, UN Chief Says in Message for International Day

By UN News

NEW YORK (IDN) — Countries which have not yet ratified the Comprehensive Nuclear-Test-Ban Treaty (CTBT) are urged by UN Secretary-General António Guterres to do so without delay.

The UN chief made the appeal in his message for the International Day Against Nuclear Tests, observed on Sunday, 29 August.

The date marks the 30th anniversary of the closure of the Semipalatinsk nuclear test site in Kazakhstan, the largest of its kind in the former Soviet Union, where more than 450 nuclear devices were exploded over four decades.

Mr. Guterres said nuclear tests caused enormous human suffering and environmental damage.

“They had terrible consequences on the health of people living in affected areas. Many were relocated from their ancestral lands, disrupting their lives and livelihoods. Pristine environments and ecosystems were destroyed, which will take decades, if not centuries, to heal.”

The closure of the Semipalatinsk test site signaled the end of the era of unrestrained nuclear testing, said Mr. Guterres. Soon afterwards, countries began negotiating the CTBT.

The treaty bans all explosive nuclear weapons tests anywhere, by any country, he added, effectively “putting a brake on the nuclear arms race and providing a powerful barrier to the development of new nuclear weapons.”

The CTBT was adopted in 1996 and has been signed by 185 countries, and ratified by 170, including three nuclear weapon States. However, it must be signed and ratified by 44 specific nuclear technology holder countries before it can enter into force.

Even though the world has witnessed the gradual development of a norm against nuclear testing in the three decades since the closure of the Semipalatinsk site, Mr. Guterres lamented that the full potential of the CTBT has not been realized.

Despite its near universal acceptance by countries, it has yet to enter into force.

“I once again urge those states that have not yet ratified the treaty to do so without delay. Eight States whose ratifications are necessary for the Treaty to enter into force have a special responsibility. At the same time, all States should maintain or implement moratoria on nuclear explosions,” he said.

“The International Day Against Nuclear Tests is an opportunity to reaffirm our commitment to outlaw all nuclear tests, by anyone, anywhere. There is no excuse to delay achieving this goal.”

The threat that nuclear weapons pose to the world remains “as realistic as ever”, said Kazakhstan’s Ambassador to the UN, Magzhan Ilyassov, speaking to UN News ahead of the International Day (interview here).

“For us, the 29th of August is not a day in the calendar. It is a reminder about how traumatic nuclear tests can be for humankind because in Kazakhstan alone, 1.5 million people still suffer, and will unfortunately suffer for future generations, from genetic diseases, cancer, leukaemia, which were caused by exposure to nuclear tests.”

Mr. Ilyassov said the total impact of the nuclear explosions carried out at the Semipalatinsk site was “1,200 times more” than the atomic bomb dropped on Hiroshima, Japan, during the Second World War.

“The test site itself is of the size of Israel, so it’s a big chunk of the territory of Kazakhstan and that cannot be used for any other purpose like agriculture for many, many decades now,” he said, adding “so with that, we can also project what was the damage caused by other nuclear test sites around the world which were eventually closed.” [IDN-InDepthNews – 29 August 2021]
