[ RadSafe ] interesting new question

[Dr. Francis Y. Tsang]

Come on!  You must be kidding....

Security Cameras produce almost no radiation.  These Vans produce x-ray
radiation no matter how low the level.  You just don't irradiation citizens
or human beings without their acceptance or knowledge.  Period!

Need to find out how is doing this!

As the doses are so low, what difference would it be from all those security
camera's in public areas?

Anyone have access to licensing procedure for these devices? such as
guidelines of operation, license application forms and requirements, etc.

questions in the justification-regulation-optimization philosophy of health
physics (I have always thought that optimization comes after regulation,
although the ICRP lists them in the opposite order). Exposing unknowing
persons to radiation (admittedly low level) to ostensibly prevent terrorism,
particularly when the exposed persons may not be citizens of the country
doing the irradiatiing, is a new balancing of risks and benefits that has
not been part of the normal equation until now. And the balance is different
if we are talking about daily screening of everything or particular
screening of containers, naval vessels, etc., in the case of a specific,
credible risk scenario. Fun stuff philosophically, frightening stuff
practically.
