Radium is a highly radioactive alkali metal. It undergoes alpha decay, which is radioactive decay by the release of an alpha particle from a nucleus. The alpha particle is a helium-4 nucleus, and it can do a lot of damage. If an individual is up against a radium source, or if he ingests or breathes radium, he will have tissues exposed to the extremely destructive radiation. That's what makes radium so dangerous. That and the fact that its radioactive decay daughters are also radioactive, and an individual exposed to radium and having that radium decay (causing biological damage) will then face the radiation hazards of the daughters of radium, because they are all radioactive, too.
The great trouble is the scarcity of water and the intense heat. Therefore, the fear of a famineâor of scarcityâwas ever present to the people. At present, however, the scarcity and cost and danger of radium will keep it in the hands of the experimenter. They should also consider what had been said about the scarcity of food and horses and the other difficulties. They were allowed two rations (only in times of scarcity they had to take the privates' fare).
