Submission + - BackScatter machines really safe? (

ameline writes: "A number of respected scientists (expert in relevant fields of study) call into question the safety of the new back-scatter screening machines.

The areas they specifically highlight are the uneven absorbtion of radiation from these machines, and the potential for mechanical or other failures to deliver even more concentrated doses than were intended. Given the cumulative nature of the risk presented by exposure to ionizing radiation, is it really wise to acquiesce to these new security requirements?

Their letter and attached memo can be found at the NPR site:
