Radium oxide is an inorganic compound of radium and oxygen with the chemical formula RaO. [1] [2] [3] Synthesis. The compound can be obtained by heating metallic ...
Radium oxide (RaO) has not been characterized well past its existence, despite oxides being common compounds for the other alkaline earth metals. Radium hydroxide (Ra(OH) 2) is the most readily soluble among the alkaline earth hydroxides and is a stronger base than its barium congener, barium hydroxide. [3]
This page lists radioactive nuclides by their half-life.
radium: 88: 1bc: Has no known biological role; as it is radioactive it is very rare. There have been various medical uses in the past. [11] Radioactive; historically, there have been many cases of radium poisoning, most notably in the case of the Radium Girls. radon: 86: 1bc: Has no known biological role. [11] Historically, there have been ...
The radiation chemistry controls much of radiation biology as radiation has an effect on living things at the molecular scale. To explain it another way, the radiation alters the biochemicals within an organism, the alteration of the bio-molecules then changes the chemistry which occurs within the organism; this change in chemistry then can ...
in physics and biology radionuclide X-ray fluorescence spectrometry is used to determine chemical composition of the compound. Radiation from a radionuclide source hits the sample and excites characteristic X-rays in the sample. This radiation is registered and the chemical composition of the sample can be determined from the analysis of the ...
Radon compounds can be formed by the decay of radium in radium halides, a reaction that has been used to reduce the amount of radon that escapes from targets during irradiation. [25] Additionally, salts of the [RnF] + cation with the anions SbF − 6, TaF − 6, and BiF − 6 are known. [25] Radon is also oxidised by dioxygen difluoride to RnF
Radiobiology (also known as radiation biology, and uncommonly as actinobiology) is a field of clinical and basic medical sciences that involves the study of the effects of ionizing radiation on living things, in particular health effects of radiation.
