Not having seen the movie mentioned, not being a real specialist in x-ray
dentistry but having experience as a dentistry patient and a "little" in
radiation protection I would like to pose the following questions:

All dental status x-raying I have undergone during decades was performed by
x-ray machines. Co-60 does not emit x-rays, but hard gamma rays, so it
cannot be used in x-ray machines. How does this cope with this obviously
silly film??? Why are these basic (deliberate) "errors" not mentioned on

Best regards,

Some other observations from last night's NCIS show (Spoiler Alert!):

At the scene where a car exploded and burned during a police chase the night
before, while having a problem using his cell phone near the burnt wreckage,
an NCIS agent observed, "I know something that could cause local RF

The old CDV-700 was brought to detect what later another NCIS agent
determined was "a minute trace of radiation" from Co-60.

Later another NCIS agent took the CDV-700 and was playfully spinning the GM
detector around by the HV cable just before entering another location to
check for more Co-60.  
And where did the Co-60 come from?  Later the agents are told by a dentist
that his 15 Co-60 units, used for dental x-rays, were recently stolen.  The
worried NCIS agents mutter, "That's enough for five dirty bombs when

[So now do-it-yourself terrorist know that all they have to do is grind up
three stolen dental x-ray machines to make a 'dirty bomb'.  ;-)]

The rest of the show and the plot ending were pretty much downhill from
