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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Major League Baseball on NBC
NBC also would normally television two prime time games during the regular season (not including All-Star Games). Generally, NBC would broadcast one game on a Tuesday and the other on a Friday. They however, would have to compete against local teams' over-the-air broadcasts, putting NBC at risk of hampering its ratings.After calling the 1988 World Series with Vin Scully, Joe Garagiola resigned from NBC Sports. Although it was not official at the time, NBC was on the verge of losing the television rights to cover Major League Baseball to CBS. Garagiola claimed that NBC left him "twisting" while he was trying to renegotiate his deal. Joe Garagiola was replaced by Tom Seaver for the 1989 season.
