A-Bomb Effects?

Question

what are the long term effects on people and land?
what would happen to the land, would there be radiation?
and if you lived through the blast, what diseases or conditions would you get?

thanks

Answer 1

In HIroshima today, you still need a special permit to dig deeper than one meter. H-bombs are cleaner (this means less dirty) because they use a lesser amount of U235 to startup the chain reaction. The dirtiest bombs can leave a land bare and irradiated for hundreds of years if not thousands, depending on the amount of U235 present in the original bomb. Again depending on the yield of the bomb, the effects will be more devastating. For a bomb like Hiroshima (15Kt), the optimal yield was reached at 580 meters and the results were the following: 70,000 people died immediately and 70,000 more died as a result of burns and lethal injuries. Then the population was plagued by cancers and birth defects.

For a bomb in the 50Kt range:

Crater Radius =185-317 ft (dry, hard rock-soft, wet soil)
Crater Depth =79-132 ft (dry, hard rock-soft, wet soil)
Maximum Cloud Radius =2.8 miles
Maximum Cloud Height =7.5 miles
Maximum Fireball Radius (FB) =0.4 miles
Minimum Survival Distance (MSD) =0.19 miles
-- =No Measurable Effect

For a bomb in the 1 Mt range:

Crater Radius = 370-660 ft (dry, hard rock-soft, wet soil)
Crater Depth = 190-260 ft (dry, hard rock-soft, wet soil)
Maximum Cloud Radius = 10.0 miles
Maximum Cloud Height = 13.0 miles
Maximum Fireball Radius (FB) = 0.9 miles
Minimum Survival Distance (MSD) = 0.5 miles
-- = No Measurable Effect

The blast stages are the following:

Flash (Light)
Thermal Flare (Heat wave)
Blast (Pressure Effects)
Fallout (Fall of Contaminants)

Why, oh why, do people keep harking back to Japans two bombs? That is as bad as trying to blame the invention of the bow and arrow!

Atom bombs come in several guises. The early bombs that everyone keeps refering to had quite long lasting effects. (But do bear in mind that those bombs stopped a war and saved far more lives than they took! That icludes those who reportedly died from the effects since)!

Modern A Bombs use far less radioactive material and the methods of building, detonating and placement of the detonation reduce radiation pollution dramatically from the old bombs.

Fussion bombs may in the future provide a totally non polluting weapon but that is a way off yet.

The nearest new technology is the Hafnium bomb which works by stimulating the release of energy from the nuclei of certain elements but does not involve nuclear fission or fusion. The energy, emitted as gamma radiation, is thousands of times greater than that from conventional chemical explosives. One gram of fully charged hafnium isomer could store more energy than 50 kilograms of TNT.

The effect of a nuclear Hafnium bomb would be to release high energy gamma rays capable of killing any living thing in the immediate area. It would cause little fallout compared to a fission explosion.

Anything less than a complete explosion would however leave any undetonated isomer to disperse as small radioactive particles. This material could cause long-term health problems for anybody who breathed it in.

The biggest danger to mankind is the harking back to the Japanese weapons. These make nuclear weapon use unthinkable don't they? Well perhaps not. The world and the anti nuclear protesters need to wake up to the fact the nuclear weapons are becoming cleaner, more efficient and - YES - possibly usable!!!!!!!! An arguament based on the old weapons is laughable. If the use of nuclear weapons is to be debated and fought against it should be with eyes wide open to the modern weapons and leave the old fashioned rhetoric out of it!!!

Answer 3

the luckiest people will die in the blast but those who aren't lucky enough to have died in the blast will be facing a world totally different from the world we live in & only the people that are willing to kill for what ever they need will servive

In the smaller countrys there wont be enough land that didn't get hit by the nuclear blast & the radioactive fallout that fallows for the unlucky servivers to grow food plus there will be no clean water to drink in these counrtys
In the larger countrys depending on how much of the country actually got hit it might be easier but still being able finding clean water will be almost impossible because for 50 yrs or more every time it rains more radiation will seep into the ground & into the water supply

Diseases, if you are radiated or expossied to the even a little fallout after a couple of days you will not want to servive. your emune system will stop work properly & you will not be capible of fighting off any disease you my already have or you catch even the comman cold will be capable of killing you

They call it MAD (mutuerally assuered destructing) for a reason

Answer 4

Just look at the historical facts relating to Hiroshima and Nagasaki.
Just keep in mind the fallout, damage and irradiation would be orders of magnitude greater.
The largest bomb dropped on Japan was only 21 Kilotons.
It takes 1000 kilotons to make 1 megaton.
The strategic bombs we have today are on the order of 50 megatons.

I have a clipping of a newspaper report dated Sept. 2 1956 headed 'A-poison in your milk'. A group of international scientists (American, British, Russian, French and Japanese) stated that every time we eat unwashed greens or drink milk we are swallowing a deadly radioactive poison (Strontium 90). 'It is accumulating in our bones and will lead to bone cancers and other diseases'. They predicted more still-births, more mental defectives and more children born with "distressing incapacities". Also stated - 'Atom weapon tests already carried out will also lead to a number of deaths and an increasing toll of disease in the years to come'. Perhaps you could visit your local library for further research now you have the date of this report. I think the newspaper was called Reynolds News.

look up cherynoble or how ever you spell it, you'll have you answers, as for this is how idiots are born
