Okay people.

Working on a small presentation on Chernobyl.

Now, I've got the data that, shortly after meltdown, the radiation was 3400 Röntgen per hour. It seems that 1 Röntgen is 258 μC/kg, with the time aspect, 1 Röntgen/hour = 258 μC/kg/h. Multiplied with 3400, that is 877 200 μC/kg/h, /1*10⁶ is 0.877 C/kg/h. Now comes the crackpoint. It seems that this is barely usable. How deadly is that exactly, and could it be expressed in other, more practical units?

Thanks.

0.877 C/kg/h?

What is C?
And h?

(God blessed anyone who don't know kg )

(Sorry, I am still learning pyshics)

Coulomb per kilogram per hour. Basically, it means that 0,877 coulomb of charge per kilogram each hour...

Are you sure those numbers are correct? If I haven't misplaced a zero anywhere, that's 3391.359R an hour, and 500R in 5 hours is lethal for humans. So this would lethally irradiate you in less than an hour.

Well, standing near a melted fission reactor CAN'T be healthy.

I recall seeing a picture of a guy who was holding a door open for his coworker when the blast happened. He survived but the arm that was holding the door open basically deterioated into a tiny lifeless limb. Was fairly horrific.

"Thanks for saving us!"
"no problem."
"Hi-five!"

You're a bitch... funny, but a bitch.

Yeah, that's pretty much it. No, actually, it literally insta-kills you in fiery gamma death.


No radiation physicians here?

(Also, my teacher forbid me to show the fun part, also known as 'the children born after'. Call me tasteless if you want)

If you'd want to say something usefull (beyond "That's going to cook the bone marrow right out of your bones and make you hemmorage all over") you'd need to find numbers in gray. the gray's the unit of adjusted radiation dose and it takes into account that alfa radiation's 20 times as dangerous as gamma radiation upon direct exposure.

[Cthulhu]

I thought it was the other way around?

[Virex]

No, Alpha radiation's actualy dangerous as hell upon direct exposure. It's just that it won't penetrate a paper bag or a few meters of air. But if you come into direct contac with an alpha radiation source then you're in trouble and god forbid your lungs or indigestion tract become contaminated with it...

The reason for this is that Alpha radiation's a lot bigger then a photon (of which gamma radiation's made). That means it does way more damage when it hits something and it also hits stuff more often. Therefor it deals more damage upon direct contact but it also makes it incapable of passing through anything at all. Gamma radiation on the other hand will pass straight through a door, but that also means that impacts are less severe and about three quarters of it will plainly pass through your body without doing anything.

It seems that alpha radiation is really stopped from pretty much anything, and is extremely nasty if it gets into your body in any way.

The problem is that gray and röntgen mean two different things.


Oh, ignore that. I wuv tha intartubes.
So, I found a figure that 115 Röntgen can be roughly converted to 1 Gy under 0°C and standard atmosphere and we'll just bypass that bullshit. So, if we divide 3400 by 115 we get...

Approximately 30 Grays.

Holy fucking shit.
That'll give you the most agonizing and messy death in your life.

Only a hazard if it's a particulate source, right?

Gah, I just realised that Gray's are the unajusted values and Sieverts are the adjusted values. Not that it matters much because the lowest adjusted value hasa  multiplier of 1 (gamma rays) and's probably the radiation you're talking about (because Alpha and Beta radiation wouldn't be able to escape from the reactor very far)
