Chemical compound
Radium sulfate (or radium sulphate) is an inorganic compound with the formula RaSO4 and an average molecular mass of 322.088 g/mol.[3] This white salt is the least soluble of all known sulfate salts.[4] It was formerly used in radiotherapy and smoke detectors, but this has been phased out in favor of less hazardous alternatives.
