NBC suit
An NBC (nuclear, biological, chemical) suit, also called a chemsuit or chem suit or chemical suit is a type of military personal protective equipment. NBC suits are designed to provide protection against direct contact with and contamination by radioactive, biological or chemical substances, and provides protection from contamination with radioactive materials and some types of radiation, depending on the design. It is generally designed to be worn for extended periods to allow the wearer to fight (or generally function) while under threat of or under actual nuclear, biological, or chemical attack. The civilian equivalent is the Hazmat suit. The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
NBC Radio Network
Near the end of the 1970s, NBC started "The Source", a modestly successful secondary network that provided news and short features to FM rock stations. In 1981, NBC created NBC Talknet, an advice-oriented talk radio network designated for the late night hours. It was one of NBC's most successful ventures in years and lasted well into the 1990s, led by advice host Sally Jessy Raphael (until her 1987 departure) and personal finance talker Bruce Williams.
