Abstract
The method and kit for detecting technetium-99m radioisotopes provide color-change solutions for visual detection of technetium-99m radioisotope-based tracers. A first color-change solution is formed from a mixture of thymol blue sodium salt solution and bromocresol purple solution. A first sample to be tested is determined to be a substance containing technetium-99m radioisotopes when the first sample to be tested turns yellow in color following spraying with the first color-change solution. A second color-change solution is formed from a mixture of bromocresol green solution and neutral red solution. A second sample to be tested is determined to be a substance containing technetium-99m radioisotopes when the second sample to be tested turns purple in color following spraying with the second color-change solution. The method and kit provide a rapid test for distinguishing a spill of radioactive TC-99m tracer from a saline spill in a nuclear medicine facility.
