>radiation exposure can be measured in square meters per square seconds
what

does this have any physical meaning?

> I have 1 apple
Ok
> I have -1/-1 apples
What physical meaning does -1 apple have?

that makes sense though because that's saying how many times can i divide my one Anti-Apple into one Anti-Apple and the answer is you can do it one time.

Joule = F*distance = N * m = kg * m^2 / s^2
So Joule/Kilogram = (m/s)^2
wtf

J/kg makes sense, yeah i can visualize that, energy being deposited over a mass

but how am i supposed to visualize square meters over seconds squared

Does radiation not deal with energy and mass?

I think it's related to how flux changes over time

Flux = density of shit over surface (square meters / second)

Since it changes over time, add another per second

Or just visualize it as joules/kg since it's more intuitive and I'm probably not entirely correct with my flux explanation

Acceleration is $\frac{m}{s^2}$ or the rate that $\frac{m}{s}$ changes per second( $\frac{\frac{m}{s}}{s}$ ) or $\frac{v}{s}$
To understand $\frac{m^2}{s^2}$ you can think about it as how thermal conductivity changes over time $\frac{\frac{m^2}{s}}{s}$ or how acceleration changes over space $m*\frac{m}{s^2}$
(keeping in mind that $F$ really = $\frac{\Delta p}{\Delta t}$ )

Unless you want to get autistic over general relativity , it is easiest to just think of it as $\frac{J}{kg}$ .

Ok I just looked at this again and it's even more retarded than I thought.

However, since it's radiation and it has meter^2, I AM sure the physical explanation is related to flux in some way.

This is why I dropped out of physics. When you get even a little bit past the extremely basic things like velocity/acceleration shit stops making sense. Just meaningless arbitrary units based off of other meaningless units.

Radiation has weird units because many different things are radiation.
Photon radiation is watts/area
Particle radiation is basically #particles/area
Its worse when they callibrate it to equivalent radiation levels by biological damage.
