Dr R.C. Williams has adopted 7500 with-plus or mimus ten per cent as his normal for
the radium workers at the Bureau of Mines. This isof course the mean of 5000 to I0000
which is taken as the usual normal limits for all conditions of mutrition.
From the facts that we have presented one would feel justified in arriving at the
conclusion that an industrial hazard did not exist in the luminous dial painting if it
a right
were not for the deaths in Orange. Two of the girls in England seem to give some indi-
cation of some exposure. Statistically also the evidence is against the assumption that
su h a hazard existed. If it were not so we would have every reason to expect to re-
ceide reports of other cases among the four or five thousand girls whorhave been engaged
in this work in Europe and this country. Furthermore cages should have made their ap-
pearances in other factories besides the Orange Pant inasmuch as these other girls
have used the same material and have worked as long in the industry
We are then brought to the conclusion that there must have been some peculiar
condition existing in the Orange Plant at the times the girls affected worked or else
the full effects of radium-thorium are not understood. As to the first offgettion we
have
no
way of telling at this date. All we can may is that we have testimony that the
girls exchange
did brushes. Pyorrhae also was common.
Turning to the second possibility we are comfronted by the fact that very little
is known of the effects of mimute quantities of radium- thorium deposited in the bones
and which may remain there for years throwing off radiations into the blood stream.
Even the matter of excretion seem to be hazy as one from reading the literature would
gain the opinion that radium ida eliminated from the body rather arapidly; omething
our experiments do not confirm.
