advising certain precautionary measures to be observed in the application
of luminous material, and we are glad to give you a copy of thege
instractions:
"1. At one time it was quite common for the operators to
point the brushes with their lips, a practice which should be strictly
forbidden. It is generally conceded that where trouble has resulted
and radio-active materials have been deposited in the system, this
practice served as the means of introducing the material into the system.
With the discontinuance of such a practice, this possibility, of course
is eliminated.
a. The work should be conducted in well ventilated and
well lighted rooms.
3. Applicators should thoroughly cleanse their hands
after handling luminous material.
4.
Applicators should refrain from placing hands about the
face or mouth when engaged in the Speration of applying this material
to instrument dials, etc.
5. Operators constantly engaged in this type of work
should have frequent (quarterly) medical exaninations. Such examinations
consisting of blood picture, and a general exmination of testh, heart,
chest and lungs.
6. A test has been developed for detecting minute traces
(as low as 2 micrograme) of radium element, when deposited in the
system. Those engaged in the application of luminous material, such as
clock companies, are having their employees subjected to this test at
various intervals in order to be absolutely assured that there is no
possibility of danger."
Assuring you that we shall be interested in the progress
of your investigation, and stand ready at all times to give you our
fullest cooperation, we are
Very truly yours,
Vice President.
