Radium (lat. radium) on maa-alkalimetalleihin kuuluva alkuaine, jonka kemiallinen merkki on Ra, järjestysluku 88 ja CAS-numero 7440-14-4. Se on radioaktiivinen, hopeanvalkoinen, pehmeä metalli, jonka elektronegatiivisuus on 0,9 ja ensimmäinen ionisoitumisenergia 510 kJ/mol. Sen löysivät Pierre ja Marie Curie vuonna 1898 Joachimsthalin (nyk.

Introducción. Las fuentes radiactivas selladas de Ra-226 han sido empleadas en Cuba Radium förekommer till liten del i uranmalmer därför att uran via ett antal steg sönderfaller till bly, och radium (226Ra) är ett av stegen. Radium sönderfaller Syftet med mätuppdraget var att uppskatta 226Ra-kontaminationen i rörsystemet och på golvet för att verifiera de uppskattningar av kontaminationen som gjordes Many translated example sentences containing "radium 226" – English-Swedish dictionary and search engine for English translations.

RADIUM-226 AND 228 What is RADIUM-226 and 228? Radium is a silvery-white metal that is radioactive. It sends out energy in the form of rays, waves or particles. It is found in nature and can exist in several forms. Radium forms when two other chemicals (uranium and thorium) break down in most rocks and soil. Radium will undergo radioactive decay.
