- Why? I'm no expert, but I think there would be little or no
- radiation release from a Nerva-style nuclear thermal rocket. And the
- release from a Nerva-style antimatter fueled rocket would depend on
- how well you can stop gamma rays.
-
- The only mechanism I can see for release in the nuclear thermal case
- would be parts of the engine getting irradiated and then eroded away
- by the propellant stream.
-
- Nervas were tested, does anyone have any figures for the amount of
- radiation (or radioactive materials) released into the environment?
