Becquerel, M. Curie, and P. Curie is awarded the Nobel Prize in chemistry for her work on radium and polonium. In the following discussion quotations from the thesis are accompanied by their page numbers in the French original.

Thesis "lntroductlon and Hlsiorlcal" Marie Curie began her work in order to study the phenom- enon in uranium that she was soon to name "radioactivitv". When she found evidence that other radioactive substances exist. In this quest she had the collaboration of her physicist husband, Pierre; who "put aside his work in progress" p 1 to join her Fig.

It was a time in which "the results of the various French and foreign researches [were] necessarily confused, as is the case with all new studies in the course of their development. The aspect of the question [of radioactivity] [was changing], so to speak, from day to day" p 2. Pierre and Marie Curie in their laboratory in Many new kinds of mysterious penetrating radiations, or rays, were heing reported.

Excessive activity in a supposedly pure compound of uranium was certainly unexpected; why In the thesis, Curie provides a table of the ionization did she not mention the anomalous activity of this "UpOs" currents observed from a variety of uranium compounds sample?

Curie knew that the measured activities3 should be pro- portional to the uranium contents of the samples, inasmuch i s Becquerel had shown that radioactivity is an atomic prop- The word "activity" was used by Marie Curie in two senses: It is therefore curious that she did not any quantitative measure of the intensity of radiation being emitted from a sample and 2 the qualitative property of emifling radiation.

This dual usage, unfortu- ty in her table of data, being content to make a later general- nately, persists today. The word acfivityis being used above by the present author in Today, the tabulated data cannot be interpreted very ac- this auantitative sense.

But because uranium is so heavy compared with 'This point could be checked by direct referenceto the notebooks. See below. If there is any shadow of U02UOs.

In fact, conclusions per se are rare in such time as they are removed by a chemical purification the thesis and are largely relegated to a brief, separate sec- nrocess.

The title of this chapter modestly suggests the develop- ment of a new method of research: That is, she did not know that the relation- property of the hypothetical substance" p As her work Apparently, certain elements were capable of signalling led her to associate the chemical properties of radium and their presence by flying a new kind of flag: Curie was quick to use this fact to invent therefore, it must have seemed exceedingly strange that what is now known as the radiochemical, or tracer, method: How had the new ele- emboldened by her success to claim "[giving] rise to a [new] ments become associated with uranium in the rocks?

Because pitchblende itself was prohibitively expensive, the Curies worked with the residues that were left after the primary removal of uranium a t the mine in Joachimsthal, Bohemia, now JBchymov in Czechoslovakia.

She warns that this figure "must. Nevertheless, her estimate is precisely the tration of the chemical prowess of Marie Curie and her correct order of magnitude, the actual factor for RaClz being associates; recovering a few decigrams of product from a few 2. This is amost remarkable final result, obtained as metric tons of starting material is a one-part-in-ten-mil- it was by applying an original electrical device to the mea- lion proposition.

This fact alone is indeed impressive. But a surement of a mysterious property of a tenth-of-a-gram simple calculation based on this statement provides a sur- sample of an unknown element, wrung by painstaking, wet- prising measure of the efficiency, or yield, with which this grand-scale separation process was accomplished.

It can be shown that when a radioactive daughter is in secular eauilibrium with a much longer lived oarent. Three metric tons of pure uranium would therefore contain 1.

But of course the ore was not pure uranium. Thus, her recovery of about 0. And this assumes that no radium was lost when the uranium was removed at the mine before she even received the residue as her startinematerial! Curie, of course, had no suspicion that there-is a fixed relationship between the amount of uranium in an ore and the amount of radium associated with it.

If she bad, she would perhaps have mentioned the ore's uranium richness. Certainly, her ulti- mate isolation of 0.
