the question of experimental error. Pig A shows a definite amount of radio-
abtive material even if minute in quantity.
That there is a retention of radium-thorium material for some time after
the exposure is indicated by an examination of the tissues of several persons
who have worked with the material. It is estimated that the bones in the case
M who had worked in the industry to within several months of her death contained
.200 mgs of radium equivalent. The tissues of a man who had been engaged in
woighing and handling the concentrated material and with an exposuro many times
greater than the case M, though he did not have much aposure during the last
year of his life, were examined. It is estimated that his tissues contained
.015 mgs at the time of his deathe
We now made an examination of living persons who had been employed or
were still employed in radium work. These persons were instructed to take a
very thorough bath the night before the test and to report at my office dressed
in clothes that had never been worn in the factory or laboratory. A person who
had nevor worked in radium was used as a control. From time to time a known
quantity of radium us placed under the person being examined and readings taken.
The person being examined was requested to lie flat on the back in a comfortable
position and the dectroscope placed directly over the chest and readings taiten
as described. The results given below are given in the number of divisions the
quartz fibre will move in one second.
