Results from Radiation Monitoring Equipment Experiment on STS-11
Abstract
The Radiation Monitoring Equipment (RME) was flown on STS-11 Space Shuttle Mission for the purpose of testing a concept for in-cabin, real-time crew dosimetry, and for the purpose of obtaining time resolved gamma-ray background data and neutron/proton background data. The RME consists of two instruments, EG&G HRM-III gamma-ray counter and EG&G Pocket REM Meter (PRM) neutron/proton dosimeter. The HRM-III was operated by the astronaut crew four times during the mission with each operation lasting 52.5 minutes. The PRM was operated twice during the mission with each operation lasting a minimum of 15 hours. The results from the HRM-III operations were plotted as a function of time and as a function of ground position. The data show large increases in count rate during periods when the Orbiter was in the East Asian Anomaly. These data are consistent with the data obtained from other missions. The RPM results are displayed in tabular form. The average dose rate from these operations is . 359mrem/hr ((2.84) x 10 to the 5th rad/hr). The total mission neutron/proton dosage predicted by these readings is approximately 60.30mrem (4.77mrads).
