It looks like the “Not In My Backyard” crowd has already started protesting the deployment of the THAAD missile defense system to South Korea:
The official announcement of deployment of an advanced U.S. missile defense system in Korea is bringing a huge backlash from residents of areas which are rumored to be candidate sites for the system.
People in the regions claim the Terminal High Altitude Area Defense (THAAD) will pose serious health risks to them and environmental damage due to strong electromagnetic waves.
Immediately after the announcement Friday, residents in Pyeongtaek, Gyeonggi Province, and Waegwan of Chilgok County in North Gyeongsang Province, the two key candidate locations, expressed vehement opposition.
A coalition of 25 civic groups in Pyeongtaek, where the United States Forces Korea (USKF) headquarters will be moved, said they will hold a press conference on July 19 to announce their protest plans to block the possible deployment there.
“The noise and electromagnetic waves emanating from THAAD radar will pose grave health threats to residents here,” the coalition said in a statement. [Korea Times]
You can read more at the link, but like most Korean protests these people are blatantly lying to get public sentiment behind them. Anyone can Google and find out the safe keep out zones for the THAAD radar. In fact it is published in the draft Environmental Assessment document for the THAAD unit on Guam that can be downloaded at this link. Here is an excerpt from the document that discusses the safe keep out zones for the radar:
Operation of the THAAD battery requires the following exclusion zones along +/- 90 degrees of the axis of orientation of the THAAD radar system to avoid injury to personnel and damage to equipment from electromagnetic radiation (EMR) emitted from that radar: 328 feet (100 meters) for personnel, 1,640 feet (500 meters) for equipment, and 3.4 miles (5.5 kilometers) for aircraft. An earthen berm in front of the radar further reduces the ground-level EMR exposure risks. For aircraft, a Temporary Flight Restriction (TFR) was established for the THAAD expeditionary mission starting in April 2013. The airspace coordination procedures for this flight restriction were documented in a Letter of Agreement between the Army, USAF, FAA, and Guam Air Route Traffic Control Center. Under Alternative 1, the TFR would continue to be used during THAAD radar operations.
So unless the THAAD radar is sitting 100 meters directly in front of someones house they will not be exposed to harmful EMR. Aircraft will need to stay 5.5 kilometers away from the radar which as the document shows on Guam they put restricted airspace measures over the radar site. These same safety measures will have to be done in Korea which I am sure USFK planners will do.
