According to the 2000 'Report of the U.N. Scientific Committee on the Effects of Atomic Radiation,' the long-lasting effects of nuclear testing can be qualified in simple scientific terms: 'Radiation exposure can damage living cells, causing death in some of them and modifying others.'

The truth is, as long as nuclear weapons exist, we are not safe.
One characteristic that I hope I never relinquish is an intense curiosity about the world around me.
I didn't appreciate how special and sometimes strange my CIA world was - until it suddenly and spectacularly ended in a newspaper column.
Of course, we all watch James Bond with envy - knowing the U.S. government would never pay for the lifestyle he enjoys.
So many times, genuine health workers and genuine NGO folks are really just trying to help other humans in whatever capacity they can. But they are perceived as being CIA, and therefore, it blocks their effectiveness.
Hair and make-up always helps. I did always try to be well-groomed, professional at all times. Take your job seriously - but not yourself.
I was working for the CIA and prohibited from speaking publicly.
Hillary stood with us, as she has stood with so many over the years, and we are proud to stand with her for our country now.
We have known Hillary Clinton both professionally and personally for close to 20 years, dating back to before President Bill Clinton's first trip to Africa in 1998 - a trip that they both acknowledge changed their lives and gave considerable meaning to their post-White House years and to the activities of the Clinton Foundation.
It's some weird idea to think that you've always got to say everything is great and perfect.
When I was happily married and found myself pregnant, I just thought that this would be just the next, normal chapter. I was absolutely thrilled. So what a surprise it was when it turned out to be the hardest thing I've ever done.
When you're in the CIA, you anticipate the possibility that you'll be betrayed by a foreign government or a source, but you never anticipate that it would be by your own government.
Any time you're a poster child for the CIA, there are a lot of people that are - either have ideological or they are mentally unbalanced - that are going to try to find you and perhaps cause you harm.
The entire intelligence community is so bloated and so reliant on contractors. There's no question there's many tasks that make sense to outsource, and yet, we have followed blindly this dogma that if it's private contracting, it must be better.
Certainly, if we had not invaded Iraq on intelligence that was clearly manipulated and cherry picked, we would be in a different position today.
We in no way are naive to think that just because Russia and the United States agree to reduce their arsenals, that everyone else will fall in line.
The Comprehensive Nuclear Test Ban Treaty, which in 1996 set out to ban nuclear tests, is an important step, but we need to do more - and we can.
I first learned the power of trust in the CIA. There is no question that when I joined the Agency as a covert operations officer, it was still run along the 'old boys' network' model.
I go to my kids' sports games and don't have to carry the enormous burden of secrecy with me every day. However, adrenaline still courses through my body whenever I go through passport control to another country.
Looking back at my career, I wish I knew then what I know now... that gender bias is built into the system, and it's unconscious in many ways. I wish I had the maturity and courage to have pushed back more. I was always trying to be a 'good girl' and play by the rules.
I know having a Jason Bourne all alone in a field firing at bad guys is much more dramatic, but it's not real.
Even those that hate Hillary admit she is a work horse and not a show horse. She gets down into the nuts and bolts and figures out, 'What's the policy, what's the substance?'
Hollywood does tend to portray CIA officers as totally the honey trap. Looks matter as they do in any profession. But the most important thing for me when I was working was blending into my environment.
I want to shine a spotlight on showing how dangerous Trump and his Twitter button can be.
After President Obama's election in 2008, there was a widespread hope that it would mark an end to unseemly partisan nastiness.
Joe and I are still very aware of the fact that we live in a country where he criticised the government and lived another day. That trumps all. To paraphrase Churchill, democracy is the worst form of government apart from all the other forms of government. You constantly have to fight for it; you have to keep your government honest.
I think it's the height of patriotism to continue to exercise your right as a citizen and to hold your government to account. Isn't that what the very essence of democracy is about?
In the CIA, they recruit you to be an officer, an ops officer, in part due to how well you cope with stress and how well you adapt to new situations.
My father was an air officer in the Second World War. My brother was a marine in Vietnam. When I was given this opportunity, I leapt at the chance because I thought it would be a hell of a lot more interesting than what my friends were doing.
For me, I thought I had the best job in the world.
I think the Bush Administration was bound and determined on regime change, and we will be paying the price of that for some time to come.
There's no way you can possibly intellectually justify, 'Well, it's okay for the Western Judeo-Christian countries to have nuclear weapons, but not for a country like Iran.' That logic goes nowhere fast.
We've made some good beginnings with the New START Treaty, but a lot more can be done.
The human and environmental devastation caused by nuclear weapons - whether by testing, mistake or malice - is the very reason we need to eliminate them altogether.
Over the years, from serving in the CIA to sitting on non-profit boards, I have observed first-hand what the addition of even one woman to a meeting or to a decision-making body can do. Put simply, in very many instances, group dynamics improve markedly.
My CIA colleagues were smart, dedicated, funny, and creative. Yes, there was sometimes stifling bureaucracy, boredom, colleagues who never should have been there, and later, deeply disturbing stories of the CIA's involvement in torture. Still, I got to do work I thought was incredibly important and, many times, had fun doing it.
I did a book event with a former colleague, Bob Bauer, and was so relieved that he said I got all the CIA stuff right.
In many, many parts of the world, being a female, you're really just wallpaper. If you take care to blend in, no one would think in a thousand years that you were doing anything suspicious.
She was very kind to us when Joe and I went through the darkest days of the leak of my name in 2003. And, of course, Joe worked in the Clinton White House.
After I resigned, I could eventually speak for myself, but when it first happened, I was in complete shock, and it took a long time for me to overcome it.
I'm not terribly confrontational, but I've gotten better at holding my ground.
When we were subjected to a vicious character assassination campaign orchestrated by senior White House officials and championed by their allies in the right-wing echo chamber, Hillary reached out to us. Her counsel during that tumultuous period was as timely as it was wise.
We need the best and the brightest to go into public service.
Donald Trump has done a lot of horrible things on Twitter. From emboldening white supremacists to promoting violence against journalists, his tweets damage the country and put people in harm's way.
I am angry when I hear things like Cheney whispering into Bush's ear on the way to Obama's inauguration to ask him to pardon 'Scooter' Libby and not to 'leave a soldier on the battlefield'. What kind of metaphor is that for his petty partisan views, when you have men and women giving the ultimate sacrifice? I have nothing but contempt.
I come from a family in which public service was something to aspire to.
A chief of station is the head of all intelligence operations in any given country.
There is no question that what we are seeing - the horrible advance of ISIS - goes back, if you will, to the original sin of the invasion of Iraq.
North Korea is the errant teenage child, aren't they? Or toddler - they're holding their breath until they get their way.
