  • UV radiation is quite damaging (although part of the popular “summer tan” culture) on its own. However, we also receive higher energy photons (above UV: xray, gamma) as well as some energetic muons from the sun. You get a 4x of a daily dose of radiation if you grab a flight. Around that of an xray. All of which is mostly ignored by people.

    You are correct that gamma ray radiation is by far the most damaging radiation. Beta and alpha radiation can be stopped by pieces of paper (or your skin), gamma radiation will go through your house, your car, your wife, hit a dna molecule in your hair follicle, and make that hair follicle permanently gray.

    More interestingly, putting the “radioactive” seawater in perspective: tritium fizzles into some beta radiation, of 18kev energy. Assuming, magically, all this (beta radiation) energy was deposited perfectly into your DNA (nearly impossible because it is beta radiation), resulting in maximal damage, in somewhere important and not the dead layer of your skin, doing a tiny calculation we can compute this damage to be that of a photon of 0.07nm wavelength (18 kev), of similar energy used in simple xray imaging (CT imaging uses 5x higher energy). With 10 becquerels / liter, 100 liters of water surrounding you, could inflict a horrible dose of 24 (hours) * 3600 (sec / hour) * 10 x 100 x 18 kev * 1.60218e-16 (Joule / kev) / 70 (kilograms per human) = 3.55958619e-9 Sv in a day

    That is a terrifying amount of 3.6 nSv. Almost close to 1/20 that of a banana you eat (I am not joking, just smiling heavily).

    The fact that people talk about radioactivity in this news, and chinese being angry and the world going apeshit is… unfathomable.


  • Do you like Trump? Or <insert local asshole politician here>?

    “Fuck <asshole person>” is one way to express to a wider forum of people a desire for change. Once you do communicate it, you can actually take action.

    Do you really think starting for example a “richtig and genau” petition without “hate speech” is better at accomplishing anything, than actually communicating a hate and working on it (hopefully); a hate that is honestly… deserved.

    If I didn’t see something like this on r/place, I might think reddit users got lulled into accepting late-stage capitalism fate.

    Fuck Spez.

    Or in more, different words: Spez is an asshole and deserves to see “his” “company” go bankrupt for his poor decisions.
