請教一題物理(輻射)

如果某個物質吸收左輻射(α/β),係唔係代表輻射仍然存在係呢個物質入面??如果唔係,咁d氦核/電子會去左邊??

感謝感謝

    α or β particles consitute "radiation" because they are moving at high speed. It is the kinetic energy that they possess causes ionization. When α or β particles come to rest, they are no longer "radiation", but behave like ordinary atomic particles.
