Abstract:
purpose: To calibrate the accurate value of 192Ir radioactivity again. materials and methods: To measure the dose rate of radioactivity in water and at air by ion chamber. results: To scale the activity of 192Ir radioactivity by air Kerma is agreement to the scaling method according to the JJG 773-92. conclusion: The investigation demonstrates that the accurate value of 192Ir radioactivity can be calibrated by the method of air Kerma.
