Jason Bell on the TSA’s Claims Regarding the Safety of Backscatter Body Scanners ★

Molecular biologist Jason Bell:

According to the TSA safety documents, AIT uses an 50 keV source that emits a broad spectra (see adjacent graph from here). Essentially, this means that the X-ray source used in the Rapiscan system is the same as those used for mammograms and some dental X-rays, and uses BOTH ‘soft’ and ‘hard’ X-rays. Its very disturbing that the TSA has been misleading on this point. Here is the real catch: the softer the X-ray, the more its absorbed by the body, and the higher the biologically relevant dose! This means, that this radiation is potentially worse than an a higher energy medical chest X-ray.

How Germany Got It Right on the Economy ★

Harold Meyerson:

It’s quite a turnabout for an economy that American and British bankers and economists derided for years as the sick man of Europe. German banks, they insisted, were too cautious and locally focused, while the German economy needed to slim down its manufacturing sector and beef up finance.

Wisely, the Germans declined the advice. Manufacturing still accounts for nearly a quarter of the German economy; it is just 11 percent of the British and U.S. economies (one reason the United States and Britain are struggling to boost their exports). Nor have German firms been slashing wages and off-shoring — the American way of keeping competitive — to maintain profits.
