Do you need radioactive isotopes I order to make an atomic weapon? Or can you just smash other atoms together to release the same amount of energy?

i would say you could use any atom. just need to release a neutron or two to get a chain reaction. the problem being it is a lot harder to do this not using a radioactive substance. in fact it is probably impossible after the initial reaction.

You can get energy by fissing stuff down to Fe or by fusing stuff up to Fe But the closer you get to Fe the hard it gets to make a reaction and the energy evolved will be less.. If you only have Fe available then make a club and bash someone.

Yeah I heard radioactive material fissed down rain after the Hiroshima bomb.

to make a fission bomb you need an unstable very heavy nucleus with weak binding energy, such that a knock from a neutron is enough to cause the atom to split – releasing more neutrons and causing a chain reaction.

You need an isotope of uranium like U235 which occurs naturally in uranium ore but in very small amounts.
They get the enriched uranium from forming a gas with the uranium ore by reacting it with flouride and then passing the gas through centrifuges where the front of the gas eventually becomes heavy with U235 flouride molecules, that is then syphoned off and chemically reacted to extract the U235.
You need about 110kg of U235 for critical mass then you can get two shaped blocks of 55kg of U235 and slam them together with conventional explosives in the presence of a neutron cloud and it should go BANG.

I believe technically it’s atomic transmutation, not splitting. The book dumbs it down quite a bit for science tards like me.

and they put that stuff in the drinking water. they’re worser than ivan milat.

The uranium and fluoride are quite safe, They only become dangerous because THEY add that darstedly dihydrogenmonoxide (which THEY also add to drinking water) . Each year more children die each year from exposure to DHMO then exposure uranium and fluoride combined.

I’ve heard you can make bombs from DHMO too.

it doesn’t matter what you think about fluoride in the water

you will have to keep drinking it

now – thats democracy in action

its a well known fact that when medicines are prescribed that they shake tonnes of the medication into the water supplies, the doctor just writes out a script something like “ 100 tonnes of Hexafluorosilicic acid taken per oz – no need to see patient or know how much they are ingesting” and the whole is then legal.

if they were so worried about peoples teeth they’d have a free dental system for everyone , dumping all that crap into the water and saying its good for you is stupid. if you tell a lie for long enough it becomes a fact.

I believe a new and revised dental plan has been tabled already and to ensure that waiting lists are also reduced for many people. I believe this was discussed in the news recently with the health minister and some points raised by the PM at around the same time as well.

I have said this before and I will say this again here. My eldest siblings were carried in utero prior to the introduction of fluoride to the water supply and through their early childhood years.

They are the ones with problems with their teeth , where as the ones born after the introduction of fluoride do not share those issues.

The nutrition otherwise was very similar if not the same… so… the only differing factor is the fluoridation which at this point coincides with issues with teeth compared with fluoride and no issues!

I would support an increase to the medicare levy for a similar dental scheme and think it is a commonwealth responsibility.

Legislative powers of the Parliament …

the provision of maternity allowances, widows’ pensions, child endowment, unemployment, pharmaceutical, sickness and hospital benefits, medical and dental services (but not so as to authorize any form of civil conscription), benefits to students and family allowances;

my guesses to build a nuclear bomb would be to source polonium and berylium to build a neutron source, that neutron source can then be exposed to some uranium.

a nuclear bomb is a waste of time really, when the enemy has one you can’t use it.

the best platform is probably submarine; in the event of a strike you can sit back and formulate a devastating counter strike. as long as those subs are on the high seas no war will happen because the enemy will find it hard to knock out the subs.

the best use for nuclear power is spacecraft, its a waste of time on earth because we are sat next to the largest nuclear powerstation in this neck of the woods – if you can’t use the sun to make power your genetic line will become extinct. it is by no mistake that practically all life on earth relies on the power of this nuclear powerstation.

you can’t use any old uranium it has to be a particular type. uranium is processd to make the nuclear radioisotope needed.

its fairly involved making nuclear weapons and probably a waste of time

with the centralisation of society means most conventional wepaons can knock out a first world society

what would happen if a handful of missiles hit australia’s handful of powerstations? no power, no water, no fuel, no food. society would go into self destruct by our own hand. the parts needed to keep power production going are specialised. it is going to be hard to do any repair with social chao going on.

>>what would happen if a handful of missiles hit australia’s handful of powerstations? no power, no water, no fuel, no food

Hahahahah I’ll be in the redoubt, unphased.

The processing doesn’t make the radio isotope needed, it concentrates it. The desired radio isotopes are present in natural uranium, just in low concentrations.

then you hit the very few fuel refineries that australia has, that means no fuel for a while until the next tanker comes in – assuming it hasn’t been taken out on the high seas with an icbm

because we have centralised everything and made the whole of society dependednt on the steady flow of even basics we are doomed. there was a clothes shortage in britain a few years ago when cheap chinese clothing couldn’t be brought in.

thats the problem with knocking out your own manufacturing capability you make yourself weak and at the mercy of anyone with industrial output.

>>unphased.<<

Well, that goes without saying, if there is no power……

there would be an exodus initially and the empty rooms would be vandalised and robbed and torched, you’d still have some residents on the lower floors doing their best but the sheer numbers of people lookign for food would be overwhelming.

exactly where will you find plutonium in nature?

Trace amounts of at least three plutonium isotopes (plutonium-238, 239, and 244) can be found in nature. Small traces of plutonium-239, a few parts per trillion, and its decay products are naturally found in some concentrated ores of uranium, such as the natural nuclear fission reactor in Oklo, Gabon. The ratio of plutonium-239 to uranium at the Cigar Lake Mine uranium deposit ranges from 2.4 × 10−12 to 44 × 10−12. Even smaller amounts of primordial plutonium-244 occur naturally due to its relatively long half-life of about 80 million years. These trace amounts of 239Pu originate in the following fashion: On rare occasions, 238U undergoes spontaneous fission, and in the process, the nucleus emits one or two free neutrons with some kinetic energy. When one of these neutrons strikes the nucleus of another 238U atom, it is absorbed by the atom, which becomes 239U. With a relatively short half-life, U-239 decays to neptunium-239 (239Np), and then 239Np decays into 239Pu.

Since the relatively long-lived isotope plutonium-240 occurs in the decay chain of plutonium-244 it should also be present, albeit 10,000 times rarer still. Finally, exceedingly small amounts of plutonium-238, attributed to the incredibly rare double beta decay of uranium-238, have been found in natural uranium samples.

Minute traces of plutonium are usually found in the human body due to the 550 atmospheric and underwater nuclear tests that have been carried out, and to a small number of major nuclear accidents. Most atmospheric and underwater nuclear testing was stopped by the Limited Test Ban Treaty in 1963, which was signed and ratified by the United States, the United Kingdom, the Soviet Union, and other nations. Continued atmospheric nuclear weapons testing since 1963 by non-treaty nations included those by China (atomic bomb test above the Gobi Desert in 1964, hydrogen bomb test in 1967, and follow-on tests), and France (tests as recently as the 1980s). Because it is deliberately manufactured for nuclear weapons and nuclear reactors, plutonium-239 is the most abundant isotope of plutonium by far.

you’d probably use plutonium for spacecraft

you could use the beta radiation to make phosphor glow and the heat to make power through the seebeck effect. you’d use it to heat water in the spacecraft

a cube ship might have the plutonium in the centre of the ship

if you could make enough electricity you could turn water into superheated steam perhaps and use it for thrust

yes but by relevancy as pertaining to nuclear bombs (the thread title) they’d use plutonium via the nuclear processing cycle not through trying to extract existing plutonium, as i said and wa smentioned in practical terms plutonium for bombs is a man made element, it is too rare in nature to extract.

online at that stupid google address.

Stalin was handed some radioactive material. He was suspicious that it had been heated in an oven. He was told on the scientists life that there was no shenanigans and he could place it under guard and in the morning and every other morning after that, it would remain warm.

i never said otherwise. i’m also saying that its made via fission that goes on in nuclear reactions. i think that nuclear powerstations make this stuff as a byproduct.

the british built nuclear powerstations to make nuclear material for bombs.

nuclear powerstations are a waste of time really, they produce too much dangerous waste and when something goes wrong you get a huge cloud of radiocative dust. fukishima has emptied the land around it.

that won’t work either

i found this

http://buffman.net/ebooks/Richard_P_Feynman-Surely_Youre_Joking_Mr_Feynman_v5.pdf

i have two copies of it somehow in my bookcase.

Sorry what procedure are you discussing Geoff and Stumpy?

Wrong thread.

a bone marrow biopsy.

me too but hey i don’t care.

;-)

just reading feynman now

he’s right

a service tech tries to understand how the thing works and then tries to work out whats going wrong and what needs to be fixed/ replaced

nowadays you rarely fix, you just pull out one part and put in another – you don’t have enough time to repair the part – its not worth it and your performance is based on how quickly you do the job and this means you do more jobs per day.

sometimes i can’t be bothered to know how something works , you just diagnose the faulty part by function or noise or some other sign and replace it.

Actually Boris, Wookie was question the vaildity of my post >>>Most plutonium is processed from U-238 rather than concentrating the trace amounts of Pu found in nature.<<< with >>>exactly where will you find plutonium in nature?<<< and then pretty much restated my post when he was shown to be wrong by others.

i only read the short posts by wookie as he tends to meander and i can’t be bothered polluting my brain with it. so if it is one line and not to big a quote i’ll answer.

by the way.. it’s pronounced noo-cle-ar..

no i asked where you’d find them in nature, i already knew that Pu for bombs is made via the nuclear processing cycle of powerstations. as i stated Pu is in practical terms a man made element.

I agree. We made it before we found it, and I doubt it exists in enough abundance to be usefully extracted.

hey tell you wha the feynman book is worth looking through

i started reading it last night and stopped at around 2

the lock picking section is interesting

i have had some distant experience with this

we had to get into a government building to do a job, examining the lock we realised that was possibly a way past it. after around 5 minutes we had got past it. it was such a good method i have used in a few other gov places where annoyingly people have locked you out and no one is there to let you in to do the job. i have seen them on other security minded buildings , if i ever had to get in it wouldn’t be too much problem.

reading feynman makes me wonder if i should get into lock picking

and no i can’t tell you what the trick is these types of lock are rife in ALL sections of the gov, it would cause to much trouble if people off the street were able to get in them, plus it would also mean that if i needed to get into the building if they changed the lock etc it would make it harder for me to get in and get the job done.

locksmiths have a device that requires them to insert a probe into the lock, they just pull the rigger a few times and bingo they are in.

as feynman points out when you tell people the problem they regard YOU as the problem
