α径迹测量,是利用透明薄膜(或35mm电影胶片)为探测器,埋设在土层中进行野外照射,积累周期为21天。探测薄片经化学药剂蚀刻后在显微镜下观察读数。α径迹量的计数以径迹密度j(个数/mm~2)表示。
α track measurement is the use of transparent film (or 35mm film) as a detector buried in the soil for field exposure, the accumulation period of 21 days. The probe was observed under a microscope after chemical etching. The count of the α track amount is expressed by the track density j (the number / mm ~ 2).
