TEST FOR RADIOACTIVITY
ON MRS. HOARE
by
Herman Schlundt
***
The tost was conducted in the laboratory of
Froderiok Flinn, College of Physicians and Surgeons,
Columbia University, New York on Tuesday, June 17, 1930.
The instruments used in these tests were the samo
ones that have served in previous tests for radioactivity of
persons suspected of "Radium poisoning". Both the gamma ray
test and the expired air tost were made.
The results of the measurements indicate that the
case of Mrs. Hoaro is to be regarded as a border line oase.
The results fix a suspicion that Mrs. Hoaro is slightly
radioactive. The total quantity of radium which our tests
indicate does not exceed two mierograms (2 g). Different
series measurements give a range of one to two miorograns
for the total amount of radium. Considering the somewhat
adverse weather conditions which provailed on the day
these moasuromen'ts had to be made, the figures given for the
amount of radium leave an element of doubt in my mind cone
cerning the positive charactor of the results. A critical
examination of the data obtained will doubtless point to the
conclusion that the values givon for the radiosctivity of
Mrs. Hosro, clearly lie within the limits of error of the
instruments used for the measurements. If weather conditions
had been more favorable for electrosecpie neasurements,
perhaps a more definite result might have been obtained,
but under the conditions of the test the experimental data.
leavos an element of uncortainty in the case of Mrs. Houre
of which I oan not divest myself.
Respectfully subnitted,
Herman Schlundt
