Question

Quizplus · Accepted Answer

I, II, and III are correct. Radioisotopes and ionizing radiation are indeed used for high-resolution imaging of tissues, were hypothesized for medical use over a century ago, and can induce apoptosis in cancerous tissues. However, they are not always selective for cancerous tissues, which can lead to damage in healthy tissues as well.
