Suspiciously similar to NASA report

I saw this article after recently reading the following NASA report, "Risk of Acute or Late Central Nervous System Effects from Radiation Exposure", obtainable from https://spaceradiation.jsc.nasa.gov/references/Ch6CNS.pdf . Most of this article, including the overall structure, subsection names, figures, citations, and body text is copied essentially verbatim from that NASA report, but the report is not cited.

Yes, it is already cited. Your mentioned report is inside Chapter 6, part of the "Human Health and Performance Risks of Space Exploration Missions" report. BTW, I have made more specific citation in the external link to avoid future confusion. Cerevisae (talk) 02:36, 19 October 2021 (UTC)[reply]

Same topic as Health threat from cosmic rays

Maybe this should be merged with Health threat from cosmic rays. It is already linked to this page via a redirect as space radiation. Is there some kind of differentiation that should be made? I like to saw logs! (talk) 04:44, 11 July 2013 (UTC)[reply]

Hi there! The differentiation is, this is specifically regarding CNS issues from radiaiton during spaceflight while Health threat from cosmic rays covers a broader range of issues and scenarios. Jssteil (talk) 04:47, 11 July 2013 (UTC)[reply]

Phosphene subjective?

In the section "Evidence" subsection "Review of space flight issues" it says, "A 1973 report by the NAS considered these effects in detail. This phenomenon, which is known as a phosphene, is the visual perception of flickering light. It is considered a subjective sensation of light since it can be caused by simply applying pressure on the eyeball.[4]"

[4]NCRP, NCRP Report No 153 (2006). Information needed to make radiation protection recommendations for space missions beyond low-Earth orbit. Bethesda, Md: NCRP.

The link is to the abstract, the entire article costs money, so I can't say if this is supported by the reference. However, it seems odd to say the least. Phosphenes produced by pressing or rubbing the eyes are not subjective, except in some extreme philosophical sense. Then there's the "radium phosphene," discovered in 1905 (since renamed "radiation phosphene"). It's what you see when holding unencapsulated radium to your closed eyelids in a dark room. It's a combination of beta particles and gamma rays inducing Cerenkov radiation in the eye. If someone can demonstrate that the source actually uses the word "subjective" then I will defer to the source, but frankly I'm skeptical. The last sentence I quoted in particular looks fishy.
