Particle track identification: application of a new technique to apollo helmets |

| Authors: | Fleischer R L Hart H R Giard W R |
| Abstract: | The Apollo helmets are being used to record the dose of heavy particles to which astronauts are exposed on space missions. An improved method for examining and identifying the etched tracks of heavy charged particles consists of replicating tracks and measuring the etching rate as a function of position along the track. Tracks have been observed in Apollo helmets that correspond to ionized atoms heavier than iron. |
