Review the chart above. What information about ultraviolet radiation supports or contradicts the safety of solar radiation exposure to astronauts on the international space? The table shows the amount of time astronauts spent on the surface of Moon during each lunar landing, and the average radiation dose they received.
Mission | Total Duration | Lunar Surface Duration | Average Radiation Dose*
Apollo 11 | 08 days, 03 hours, 13 minutes | 21 hours, 38 minutes | 0.18 rad
Apollo 12 | 10 days, 4 hours, 31 minutes | 31 hours, 31 minutes | 0.58 rad
Apollo 14 | 9 days, 1 minute | 33 hours, 31 minutes | 1.14 rad
Apollo 15 | 10 days, 1 hour, 11 minutes | 66 hours, 54 minutes | 0.30 rad
Apollo 16 | 11 days, 1 hour, 51 minutes | 71 hours, 2 minutes | 0.51 rad
Apollo 17 | 12 days, 13 hours, 51 minutes | 74 hours, 59 minutes | 0.55 rad
*Average radiation dose information can be found on the Life Sciences Data Archive at JSC3
3. From the radiation data of past space missions (above), what concerns should future astronauts have about living in space for long periods of time? (Support your answers content from the lesson.)
4. Based on your knowledge of particle and ionization energy, are any of the claims made in the excerpts valid and reliable? Explain your reasoning for both claims.
