dabateman Posted June 2, 2020 Share Posted June 2, 2020 This recent paper is very surprising and if confirmed may have huge impact. https://www.nature.com/articles/s41598-020-65955-5 Link to comment
Stefano Posted June 2, 2020 Share Posted June 2, 2020 They are probably much safer than X-rays, so I think they will replace them in some applications. Link to comment
Stefano Posted June 2, 2020 Share Posted June 2, 2020 I saw the same article in Italian, without searching for it. Maybe this discovery is quite important. Link to comment
dabateman Posted June 3, 2020 Author Share Posted June 3, 2020 If true will add fire to the anti cellphone and wireless radiation movement. But 30 minutes is longer than anyone should be in a scanner for. So the direct impact where we use THz waves shouldn't be affected. Its the twist on similar frequencies that will push this. But intensity and duration matters, and that might get lost. Link to comment
Andrea B. Posted June 3, 2020 Share Posted June 3, 2020 Somebody should add a summary and the paper link to the Wikipedia article. Reveiw for me please, are Terahertz waves currently used in any device? I did not read the paper, and I do not know about Thz. Thanks!!Always trying to learn. Not sure I always do. Link to comment
Stefano Posted June 3, 2020 Share Posted June 3, 2020 THz technology is in its beginning, and THz waves are difficult to generate and detect. There are millimeter wave scanners in some airports, but usually THz waves are considered to be about 10 times smaller in wavelength. They can penetrate clothes and thin materials, and thus they can be used to find hidden metal objects just like X-rays, but, unlike them, they are (?) safe, as far as we know. Link to comment
