[ RadSafe ] interesting new question

Wed Oct 27 23:02:49 CDT 2010

If your work requires daily passage through the Z-Portal at entry and exit, then you would only add two days equivalent to a full year of natural background radiation, or make your day 24.13 hrs of background radiation.

This is based on data published in this report:

DRAFT Environmental Assessment for
Deployment of Z® Backscatter Screening
Systems, San Ysidro Port of Entry
San Diego County, California
March 2008
U.S. Customs and Border Protection

If it is not - and in my country it would be absolutely illegal and would cause an outcry of public opinion if it were known - then it has to be stopped at once unconditionally. If it were legal, opponents could only try to have  the relevant regulations reversed. Personal preferences do not count!
