Radioactive Decay
2 Q’s at start = half-life

slide 4
How can it be used?
Space Exploration!!!!!


How do they travel so far (energy for onboard systems)?

Slide 5
What types of energy are used?

One energy source is from RTGs onboard spacecraft

Slide 6
Radioisotope Thermoelectric Generators (RTGs)

slide 7
RTGs and Radioactive Decay
The RTGs power the spacecraft through the radioactive decay of plutonium-238.

slide 8
RTGs and Radioactive Decay
This decay emits heat, which is converted into electricity for the spacecraft to
"see, sense, hear, and speak."

This power supplies a reliable, long-lasting source of electricity which is
insensitive to the chilling cold of space and virtually invulnerable to high
radiation fields, such as Earth's Van Allen belts and Jupiter's magnetosphere.
