Richard Savage will talk about his experiences when he travelled to Japan in August this year to attend a conference and events commemorating the 80th anniversary of the dropping of atomic bombs on Hiroshima and Nagasaki.
An estimated 70,000 were killed instantly, and over 140,000 are believed to have died of the after effects.
Richard will consider the implications of the decision to use these weapons, and there will be an opportunity for discussion following the talk.
