While the uranium and radium in fluorosilicic acid are known carcinogens, two decay products of uranium are even more carcinogenic: radon-222 and polonium-210.
Radium decay product radionuclides, such as Pb and Po, are also much more particle reactive and less likely to be extracted through the unconventional drilling and hydraulic fracturing process than decay-series parent Ra isotopes.
To do so, they measured nickel-60, a decay product of iron-60, in eight meteorites known to have formed at different times during the first 3 million years of the solar system.
Magnesium makes a particularly good marker for planetary origins because, first, isotopes of magnesium can be separated during evaporation and condensation in the solar system and, second and more uniquely, one isotope of magnesium, Mg26, is a decay product of Al26, which existed in the early solar system for less than 5 million years.
Worse, a reanalysis of the original data showed no evidence of either element 118 or its decay product, element 116.
Although the aluminum-26 present in the early solar system has by now disappeared, researchers can infer its presence by measuring its decay product, magnesium-26.
Fisher of PNNL finally constructed a cage for the alpha emitter radium-223, a decay product of actinium-227.
But researchers calibrate PET scanners with a decay product of germanium-68.
One of the isotopes, neodymium-142, represents in part the radioactive decay product of a form of the element sumarium, which was present only during Earth's earliest epochs.
Its draft risk assessment points to radium-226, a decay product of uranium-238, as the principal isotope of concern.
Tickets for the masterclass with Danielle, which will be held in Debenhams, Argyle Street, are PS25 and are redeemable against an Urban Decay product on the night.
