Clarins: spray to "protect skin from the harmful effects of electromagnetic waves"
[edit]Clarins are selling a new facial spray called Expertise 3P, which claims to protect the skin from the harmful effects of electromagnetic waves, specifically those "produced by different types of domestic communications equipment". They claim to have grown skin cells in the lab and exposed them to 900 MHz (signal strength not given) and seen changes in the skin cells. The ingredients in this spray are claimed to reduce the changes. Unfortunately this is not published yet but is it remotely plausible that our skin is being damaged daily by mobile phone and TV signals etc?! —The preceding unsigned comment was added by Purple (talk • contribs) 17:22, 20 February 2007 (UTC).
- Seems unlikely, but couldn't say for sure. UHF is non-ionizing and the wavelength is pretty big compared to skin cells. I'm inclined to believe this spray is naught but snake oil but who knows!? 216.24.45.28 (talk) 18:37, 17 March 2022 (UTC)
"people are calling"
[edit]"The FCC has allowed Americans to connect any device and any application to the 22 MHz of radio spectrum that people are calling the 700 MHz band. " I'm not entirely sure what this is trying to say, but "people are calling" is definitely not proper encyclopedic language. --Khajidha (talk) 14:59, 30 March 2020 (UTC)
- Indeed. The paragraph in question is a reference to a polemic over the 2008 United States wireless spectrum auction. The language is wrong in many other ways: (1) presumes familiarity with current events of 2008; (2) "any device and any application" is in the context of LTE mobile telephony networks, not just any use of the frequency; (3) "22 MHz of spectrum" is actually the upper block C of the 2008 auction, which corresponds to 3GPP Band 13; (4) the 700 MHz band in question is the range from 698–806 MHz, which appears to be standard usage at least in the USA (FCC). Given the existence of the specific article on the question, the fact that the paragraph refers to current events of over a decade ago which are largely forgotten, and the irrelevance of the issue to the main content of this article, I think this paragraph should simply be excised. –– Justinbb (talk) 23:11, 2 June 2021 (UTC)
- I've cut the paragraph in question. --User:Khajidha (talk) (contributions) 14:55, 8 September 2022 (UTC)
