What's the meaning of NBC?
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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
On March 1, 2012, Dial Global announced that it would discontinue CNN Radio, and replace it with an expansion of NBC News Radio on April 1, 2012. This marked the first time since Westwood One's purchase of NBC Radio and its properties that NBC would have a 24-hour presence on radio. A previous program, "First Light", placed new emphasis on the NBC brand after diminishing it over the years. With the change, NBC News Radio expanded its offerings from 60-second news updates airing only on weekdays to feature two hourly full-length newscasts 24 hours a day. Subsequently, on September 4, 2012, Dial Global launched a sports-talk radio service, NBC Sports Radio.
