The Curies were both exposed to radiation and were the first persons to suffer from radiation sickness, resulting in an early death for Marie. Pierre was killed in an accident with a horse and carriage. Marie s notebooks are still radioactive.

Marie-Pierre Krafft at the Institut Charles Sadron, Strasbourg, has studied the polymerization of hydrophobic monomers such as isodecylacrylate (ISODAC) in small rmil-amellar vesicles of perfluoroalkylated phosphatidylcholine (F-PC). The process was compared with that for polymerization of ISODAC in egg PC vesicles. In the case of F-PC vesicles the formed pol3mer was homogeneously distributed throughout the vesicles whereas for egg-PC, parachute polymerization was found to be operative. Ferro and Krafft have also studied the effect of addition of semi-fluorinated alkanes (C jH2 j+iC F2 +i, H jF ) such as HioFe on Ca -induced fusion and the rate of release of 5,6-carboxyfluorescein referred to as (CF) from the water cores of the vesicles. For HioFg, the rate of fusion was reduced by an order of magnitude, and there was a 40-fold decrease in the rate of release of CF, as compared with phosphatidylserine vesicles as a reference. 

Finally, my wife, Marie-Pierre, is to be thanked, for her patience and moral help all along these years. 

So, we see as a laboratory source of alpha particles the supply would be pretty constant over a long period of time. Another consideration is that radium is in the same column of the periodic chart as Ca and so biologically it might have similar chemistry to Ca and become trapped in bone tissue where it would be radioactive for a long time. Thus, this interlude regarding the fact that first-order decay is a useful model for nuclear processes has provided an opportunity to discuss some aspects of nuclear chemistry. Considering the crossover of physics and chemistry in the work of the Curies (Marie, Pierre, and Irene) and information in the popular domain regarding nuclear chemistry, we think this brief discussion is justified as an essential part of physical chemistry.
