Novichok in Chemical Warfare

Guest: Peter Chai, MD, Medical Toxicologist, Brigham and Women's Hospital in Boston, MA and Assistant Professor, Medicine, Harvard Medical School Russia continues to deny it had anything to do with the attempted assassination of Sergei Skripal – a former Russian spy living in the UK. Both Skripal and his daughter survived serious illness after exposure to a nerve agent British officials say was Novichok. Weeks later, a British woman named Dawn Sturgess died from Novichok poisoning. Police think she somehow came into contact with the nerve agent intended for Skripal. British officials have called the attack an unacceptable act of aggression.
