根据第二段中的“Then, in 1911, after much personal tragedy (Pierre Curie had died suddenly in 1906), Curie was awarded the Nobel Prize for Chemistry for isolating pure radium. She would go on to devote her research to the study of the chemistry of radioactive substances as well as their...

We all know water is supposed to hydrate and nourish us, but these days, it’s also carrying a heavy load of contaminants. Radioactive elements like uranium and radium. Heavy metals like lead and mercury. Chemicals from industrial waste, pesticides, and even pharmaceuticals. All of these ...
Even more ominous for Darwinists was the emergence of the “mutationists” in the 1910s, a school of geneticists whose star exponent, Thomas Hunt Morgan, showed that by breeding millions of fruit flies – and sometimes spiking their food with the radioactive element radium – he could produce...

from. In fact, to this day, it is still quite unexplained where this energy comes from.” Another scientist, a chemist living in France, Marie Curie, won two Nobel medals for her work with radioactivity; she discovered the elements ʻradiumʼ and ʻpoloniumʼ [contained ...
It is interesting to note that not all granitic regions are prone to high emissions of radon, Aberdeen, for instance, commonly known as the Granite City, is situated on very radium rich rock. Radon gas is measured in Becquerel’s per cubic metre and, according to UKradon (the UK’s refe...
It is not extremely toxic, it is not highly radioactive (as the picture suggests), it is not hazardous to handle a consumer product made with lead solder, it hardly leaches into the environment from landfills, it is widely used in much higher volumes in things like car batteries, and ...
