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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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 Olympic broadcasts
Traditionally, NBC has primarily televised marquee sports in its Olympic coverage. When the network added coverage on its cable partners in 2000, it allowed them to televise other sports. 2004 marked the first year that they televised all 28 sports in the Summer Games. In 2008, aided with online streaming, NBC aired many of the events held at the summer games live.
