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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
On November 28, 2011, "First Light" once again began identifying throughout the program as coming "on NBC Radio from Dial Global/the Dial Global Radio Network". While the conclusion still aired the Dial Global network sounder (an audible chime not identifiable with NBC), this marked a re-emphasis of the "NBC" brand. On March 2, 2012, Dial Global further announced it would discontinue distributing newscasts from CNN Radio and make NBC News Radio a full-time operation. This marked the first time since 2004 that full-length radio news was presented under the NBC banner. On April 1, 2012, in a reversal of the original NBC Radio Network's dismantlement, the majority of CNN Radio affiliates were switched to NBC. The new format consisted of 6 minute on-the-hour and 3 minute on-the-half-hour newscasts.
