Mass Radiography.—In London, Mass Radiography was
originally carried out under the direction of the London County
Council, but since January, 1948, the responsibility for this service
has rested with the South East Metropolitan Regional Hospital
Board.
Introduced primarily for the early detection of Tuberculosis,
the Mass Radiography service is responsible for revealing many
other chest malformations and disabilities which would doubtless
have remained undetected perhaps for years.
As a direct consequence of the diagnosis of these ailments
treatment is made possible at a very early stage, thereby enabling
a much more favourable prognosis to be entertained.
Two surveys by the South East London Mass Radiography
Unit were carried out during the year. The first, on 3rd August, was
in respect of the Operators at Blackheath Fair and the second on
12th and 13th November, was in connection with a large factory
in the area. I am indebted to Dr. J. M. Morgan the Director, for
the following analysis of the results :—
