Collection Item Summary:

This small tube contains remnants of the materials used in the passive radiation dosimeters used by astronaut Neil Armstrong on the Apollo 11 mission. The passive dosimeters were placed around the astronaut's body - on the ankle, thigh, and chest - to measure the exposure to cosmic radiation throughout their mission. The materials were analyzed after each mission to determine the dose and type of radiation experienced.

NASA transferred this tube to the Museum in 1970 with other Apollo 11 equipment.
