Did Astronauts Face Dangerous Radiation During Apollo Missions?

AI Thread Summary
Astronauts on the Apollo missions were exposed to cosmic radiation, but the levels were relatively low, ranging from 0.16 to 1.14 rads, which is below the annual safety limit of 5 rem set for radiation workers. The missions lasted only a few days, minimizing exposure risks, despite the lack of a magnetic field on the Moon. The radiation levels increased significantly above Earth's magnetosphere, particularly near the Van Allen belt, but were manageable for short durations. For future long-term missions, such as to Mars or a lunar base, radiation exposure remains a critical concern. Overall, Apollo astronauts did not face dangerous radiation levels during their missions.

ello,
there is a knowledge that above Earth's magnetosphere cosmic radiation is extremely high and unsafe for human life.
the lowest point of Earth's magnetosphere is 70.000 km,
the range between Earth and moon equals ~380.000 km,
we know that moon doesn't have own magnetic field.
So my question is -was astronauts damaged by cosmic radiation during appollo missions.
if not-why?

Radiation increases with height even on the surface of earth, rises significantly once you reach the Van Allen belt and drops again afterwards.
For long journeys (to Mars, for example, or for a permanent base on Moon), this is a significant issue. For a few days, the radiation level is acceptable.

Wikipedia said:
The total radiation received by the astronauts varied from mission to mission but was measured to be between 0.16 and 1.14 rads (1.6 and 11.4 mGy), much less than the standard of 5 rem (50 mSv) per year set by the U.S. Atomic Energy Commission for people who work with radioactivity.
 
ty very much for link and answer, this is very interesting to know
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
