In the wake of WWII there was an alarming rise in Tubercolosis cases
in the UK and the Ministry of Health decided that Mass Radiography was
the way forward. Accordingly, Mobile Mass Radiography units were sent
to schools, factories and to local access points.

There was also a huge promotional campaign which resulted in a large
percentage of the population being 'screened' (or bombarded with
xrays).

The campaign was quietly dropped when it was discovered that the
methodology was not effective and that it may have being doing more
harm than good.

Now, studies have linked the incidence of breast cancer to chest xrays.

But has anyone linked Mass Radiography in the UK to its likely effect
on the incidence of breast cancer or any other cancers?

Many thanks

Do you remember those Clarkes X-Ray machines they used to have in all
their shoe shops ?

Indeed I do, Jerry.

I wonder why Clarks stopped using them.

The danger was not to the customers but to the untrained 
lowpaid staff in the shoe shops

Good point, Kemlo!

These days when xrays are taken (here in the UK), the operative takes
cover behind a special screen.
