A box containing a radiation detection kit is shown in the cold-war era nuclear fallout shelter constructed for U.S. President John F. Kennedy on Peanut Island near Riviera Beach, Florida November 8, 2013. The dingy, cavernous steel fallout shelter hastily built on a man-made island off Florida's east coast is a stark reminder of the harsh realities President John F. Kennedy faced from the first days of his presidency at the height of the Cold War. Picture taken November 8, 2013. REUTERS/Joe Skipper (UNITED STATES - Tags: POLITICS)
