Abstract
A method of measuring radium by {alpha}-inner scintillation is introduced, which is similar to the detection of scintillation chamber with zero volume. The formation of samples and scintillation substances is also similar to {beta}-liquid scintillation but it is mixed between solids. By this method the radionuclides are absorbed, filtrated, dried and evenly mixed with ZnS(Ag), then sealed up for measuring. Under specified conditions and in the range of 4{approx}8 MeV ({alpha}-energy), the 4{pi} detecting efficiency is 95{+-}1%. It can rapidly measure {sup 226}Ra in samples taken from uranium ore processing. The determination cycle for batch processing (6 samples and in liquid) is about 6 hours. It can also measure {sup 226}Ra and {sup 224}Ra in environmental samples of soil, water and biology. The determination cycle is 4{approx}6 days that is less than half of the cycle of emanation method and the detection limit is 1.5 x 10{sup -4} Bq.
