Science writer Sophia Chen provides a straightforward explanation of how radiation therapy machines work and why the new linear accelerators (linacs) are safer and better than the old type that uses radioactive material. She shares some disturbing stories about radiation accidents that happened when old machines ended up in the junkyard, explains why developing nations need new machines adapted for their environments and identifies who is helping to achieve that goal. getAbstract recommends Chen’s analysis to anyone with an interest in health care in developing nations.
In this summary, you will learn
- How modern linear accelerator (linac) radiotherapy machines differ from older isotopic machines,
- Why linac machines are better and
- Why developing nations aren’t replacing isotopic machines with linacs yet.
