裂变径迹定年中子注量的测量

  • 摘要: 利用钴活化箔测量绝对中子注量,对SRM962标准铀玻璃进行多次刻度,得到刻度因子B=(5.76±0.32)×10~9/径迹。用裂变径迹年龄标准样品进行检验的结果表明,利用该标准铀玻璃可以获得较准确的中子注量和定年结果。

     

    Abstract: SRM 962 standard uranium glass are calibrated against Co activation monitors in nine irradiations.The calibration factor is found to be(5.76±0.32)×10~9 neutron/track. Age standards are employed tocheck the accuracy of neutron fluence and the results show that more accurate fission track ages can bedetermined using the calibrated SRM 962 standard uranium glass.
