    It is the disintegration chain of each atom and the particules and half life of all.

    Half life is the time it takes for half the atoms to disintegrate. The first letter is the emited radiation (alpha, beta, gamma).

    You can derived how dangerous each of these materials is from these informations.

    On a quick glance, radium should be the deadliest one, because the half lives are all very short, so that’s a lot of deadly radiations. On the other hand, uranium is said to be on a critical mass, which could be a chain reaction.


  • You can survive with many external means. But that’s the thing: you need external means to survive because you cannot survive otherwise in this environment.

    And yes, even in dry weather doing work in direct sun when temperature is over 40C is madness. Even a healthy adult can die in this environment. You should at the very least have proper garments and drink a lot.


  • That’s why we’re starting to use wet bulb temperature to measure these things. This is the temperature measured with the measuring bulb of the thermometer wet, so it accounts for wind and humidity, and it reflects how humans would feel and survive.

    38°C wet bulb is a deadly temperature. Not like you may die if you are unlucky or have specific condition, but like healthy you adult humans die in this weather. Because wind and humidity are such that your body cannot cool itself.

    In more temperate or dry places the heat should not be an underestimated danger either. But indeed the danger comes more at 40°C and higher and specific circumstances (stupidity being one of them).





  • It’s not whining. It’s not doomerism. We need to fight indeed. But it’s not for a better future. It’s for the future to not get too bad.

    And in a world where 60+ years old a more numerous than 25- yo, it is important to make them understand where their shitty usual vote is taking us. For us to have a chance, the 60+ need to change their vote or to stop voting.




  • Dude, life is already going extinct. Cats are mostly extinct already, and most animals are either robots or uber expensive clones! There are no animals in wilderness. There are acid rains and all sort of climate problems because the climate is already in shambles.

    Cops will definitely kill you on a whim. Or it will be one of the gangs or corpo who will. Didn’t you see the shootings in pacifica?

    Religion is very much there with a guy who crucifies himself on a braindance!

    Cyberpsycho would be killed on sight of Regina wasn’t hiring you to extract them. Did you watch any of the media of CP77? It seems like you didn’t.

    Did you hear about the corpo wars? CP77 is about the start of a war between arasaka and militech btw…
