Den är den Halveringstiden för 226Ra är 1600 år, vilket gör att aktiviteten från vår källa är praktiskt Barium-133 and radium-226 were used as radiotracers and their concentrations in the aqueous phase were measured using liquid scintillation counting and The activity, mainly Ra-226, in the scales in the systems are often at levels classified as low level radioactive waste (LSA) in the industry.

Some of their ggyamma rays are of high energy. •Ra-226 is readily assimilated by the body (f1= 0.2) Radium is placed under the group 2 of alkaline earth metals in the periodic table. It has 25 isotopes, amongst which radium-226 is the most common, having half-life of 1,622 years. It is the most stable of all the radioactive elements. It appears as brilliant white element with luminescence.

radium-226 and radium-228 (226Ra, 228Ra) in drinking water. PHGs are developed for PHGs are developed for contaminants based on the best available toxicological data in the scientific literature. Ra-226 and its short-lived decay products are the most radiologically significant ra dionuclides associated with uranium ore because: •The external gamma hazard is primarily due to Pb- 214 and Bi-214.
