Wake Up Idaho guest today is Tona Henderson, an advocate for Idaho Downwinders.You might have to ask what is a downwinder, before you can answer if you are one. Here is a clue – it has to do with nuclear testing in the Nevada desert that started in the 1950’s and continues even now. The latest test was conducted 85 miles northwest of Las Vegas. Scientists performed and underground nuclear experiment, just short of a nuclear blast on 02/21/06. You do not have to be an Idahoan to be a downwinder.
