Hiroshima and Nagasaki: 7 Things You Should Know

3 August 2018 (ICANInternational Campaign to Abolish Nuclear Weapons)* – Next week marks 73 years since two atomic bombs were dropped over the cities of Hiroshima and Nagasaki. Hundreds of thousands of people were killed and maimed, and the effects are still being felt today.

But while the mushroom clouds became iconic symbols of mass destruction, and the paper cranes a symbol of hope for a nuclear-free world, there are many things you may not know – or may have forgotten – that are really important if we’re going to make sure this never happens again.

#1 More than 210,000 people were killed

By the end of 1945, the bombing had killed an estimated 140,000 people in Hiroshima, and a further 74,000 in Nagasaki. In the years that followed, many of the survivors would face leukemia, cancer, or other terrible side effects from the radiation.

“Each person had a name. Each person was loved by someone. Let us ensure that their deaths were not in vain.”

– Setsuko Thurlow, survivor of the August 1945 atomic bombing of Hiroshima
Nobel Peace Prize acceptance speech, December 2017

#2 The bombs were detonated in the air

Bombs don’t have to hit the ground in order to detonate. For nuclear weapons, detonating them in the air causes the blast to have a larger geographical impact. Both “Little Boy” (the uranium bomb dropped on Hiroshima) and “Fat Man” (the plutonium bomb dropped on Nagasaki) were detonated in the air.

You can find out more about what impact a detonation on the air or on the ground would have on your city through the Outrider Foundation’s powerful (but terrifying) interactive tool:

#3 First responders couldn’t help back then, and they wouldn’t be able to help now.

If a nuclear weapon were to be detonated over a city today, first responders – hospitals, firemen, aid organisations – would simply be unable to help. This powerful video by the Red Cross explains why:

Tthe reason we know this is that the extent of the damage in Hiroshima and Nagasaki in 1945 made it nearly impossible to provide aid. In Hiroshima, 70% of all buildings were razed and burned, 42 out of 45 hospitals were rendered non-functional and 90% of physicians and nurses in were killed or injured.

In Nagasaki, ground temperatures reached 4,000°C and radioactive rain poured down.

As a result, most victims died without any care to ease their suffering. Some of those who did enter the cities after the bombings to provide assistance later died from the radiation.

#4 The effects last to this day

It takes around 10 seconds for the fireball from a nuclear explosion to reach its maximum size, but the effects last for decades and span across generations. Five to six years after the bombings, incidence of leukaemia increased noticeably among survivors.

After about a decade, survivors began suffering from thyroid, breast, lung and other cancers at higher than normal rates.

Pregnant women exposed to the bombings experienced higher rates of miscarriage and deaths among their infants; their children were more likely to have intellectual disabilities, impaired growth and an increased risk of developing cancer.

And for all survivors, cancers related to radiation exposure still continues to increase throughout their lifespan, even to this day, seven decades later.

#5 The Paper Cranes are symbols of peace and action

Paper cranes are a traditional Japanese symbol for good health, but they have also come to symbolize the Hibakusha – the survivors of the bombings. From the iconic story of Sadako’s 1000 paper cranes to the tireless efforts by Hibakusha to rid the world of nuclear weapons to this very day, their stories are stories of hope and determination that must not be lost.

Survivors of the atomic bombings of Hiroshima and Nagasaki are living witnesses to the horror of nuclear war and when we talk about nuclear weapons, we must talk about the real unacceptable effects they can have on human beings.

The paper cranes are not just a symbol of peace, but also a call to action. They are a reminder that we must keep pushing to see the #endofnukes.

To learn more, you can find a vast number of Hibakusha testimonies online, but good starting places are Hibakusha Stories and the 1945 project, as well as these resources by the Hiroshima Peace Memorial Museumand the Nagasaki Atomic Bomb Museum.

#6 There is a way to make sure it never happens again: the Nuclear Ban Treaty.

On July 7th, 2017, the UN adopted theTreaty on the Prohibition of Nuclear Weapons. This historic treaty bans nuclear weapons and all activities related to them. One it enters into force, this legally binding treaty will prohibit nations from:

  • Developing
  • Testing
  • Producing
  • Manufacturing
  • Transferring
  • Possessing
  • Stockpiling
  • using or threatening to use nuclear weapons
  • or allowing nuclear weapons to be stationed on their territory.

The treaty also prohibits states from assisting, encouraging or inducing anyone to engage in any of these activities and is the first international agreement on nuclear weapons that makes countries take action on the health and environmental legacies of past use and testing.

But the impact of the treaty also extends beyond its legal implications. With a ban in place, it becomes easier for all those who oppose nuclear weapons to call out those countries and institutions that carry out nuclear-weapons related activities.

Every time someone speaks up against nuclear weapons and says: “I believe nuclear weapons are inhumane, immoral and illegal. All countries should join the Treaty on the Prohibition of Nuclear Weapons” it chips away at their legitimacy.

This kind of stigmatisation has been incredibly successful in the past, for the elimination of other weapons – such as landmines and chemical weapons – to changing social norms around behaviours – such as smoking.

If we all keep pushing, we can create a world where nuclear weapons are an unacceptable, nearly unbelievable thing of the past.

So say it, loud and say it often. And if you’re in a country that endorses nuclear weapons, demand change! You can find 5 concrete ways to take action here >> 

What's next: We have the nuclear Ban Treaty, here's who we're going to achieve it's purpose

#7 Countries around the world: hear the calls of the Hibakusha, join the Nuclear Ban Treaty

After decades of campaigning for a world free of nuclear-weapons, the Treaty on the Prohibition of Nuclear Weapons holds great significance for the Hibakusha.

A recent survey among 6000 Hibakusha carried out by Kyodo News showed that a vast majority feel that Japan should join the U.N. treaty banning nuclear weapons, underscoring their discontent with the government’s opposition to the agreement.

Joining the treaty would represent a recognition by Japan of its affected citizens’ rights and suffering – continuing to oppose it on the other hand could be seen as a rejection of these.

The #nuclearban will enter into force when 50 countries sign and ratify the treaty. World leaders must heed the calls of Hibakusha, and of concerned citizens around the world, for a nuclear-weapon-free future.
