Ionising Radiation and Clinical Practiceoresponsiveness has been mentioned already, in relation to both tumours and normal tissues. The aim of the doctor using ionising radiation in the treatment of tumours is to kill the tumour and not damage the normal tissues. While this is desirable in theory, it is difficult to achieve in practice. I作者: Mawkish 時(shí)間: 2025-3-22 14:30 作者: Mawkish 時(shí)間: 2025-3-22 18:26
