Breast cancer clusters around airports and military bases and chemical dumps.

The scanner system emits a pencil x-ray beam that rapidly moves across the body from toe to head. A small fraction of the x-rays is scattered off tissue and clothing to sophisticated detectors. The bulk of the radiation is absorbed by the body damaging proteins and DNA. To date, all calls for a truly independent assessment have been thwarted; TSA has even given Congress the run around. What are they hiding? 

Backscatter security scanners focus an intense x-ray beam at your skin looking for "terrorists." The next proposed generation of covert scanners claims it can check you for skin cancer and drugs at a distance.

After ten years 480 billions were spent on a homeland security, and not a single "terrorist" has been captured. Hundreds of thousands killed and injured in five wars on terror with 7,000 billions spent. While our rail, bridges, water and infrastructure fall apart around us, putting us all at risk, are we safer ten years later?

Radiation is becoming more common in the environment and can be a significant risk to human health. Airline pilots, industrial, power and defense workers often operate in high radiation environments. Medical, dental, veterinary, chiropractic industrial and security imaging are using more radiographic techniques. Accidental and intentional releases of radiative materials is a increasing concern for many. Devices to warn and accurately quantify radiation dose rates and total exposure are needed.

Following the release of a May 2012 report, newspapers around the world advertised headlines announcing that the World Health Organization (WHO) assumes that Fukushima radiation emissions pose minimal health risk. Based on an assessment of published emissions of radioiodine and cesium up through September 2011, Japan’s nuclear meltdown poses no serious cancer risk, except for localized exposures around Fukushima prefecture, which may result in increased danger of thyroid cancer.

In the event you were planning on putting an atomic bomb in your pocket during your next flight you may get caught. Never mind congress has cleared the way for nuclear powered unmanned drones to fly over our heads and look in our windows.   Forget that thousands of hand held surface to air missiles some us made are missing from the various wars on terror. And our troops are inhaling depleted uranium (DU) dust.
