The Martian: Hot Stuff
  • Science → Energy → Radioisotope Thermoelectric Generator
  • Chemistry → Atoms → Radioactive Isotope

Astronaut Mark Watney digs up the buried radioisotope thermoelectric generator (RTG) so that he can use it as a power source for his heater. He explains the dangers of using an RTG near humans.

Public Discussion Questions


  1. Why does Mark wrap the radioisotope thermoelectric generator in foil?
  2. Mark states that radioactive isotopes are dangerous to humans. Why is this true?
  3. What elements, aside from plutonium, could the radioisotope thermoelectric generator use?
