hastily made nuclear weaponsAnswer:Regular explosives together with radioactive material, not strong enough for a nuclear explosion, but spreads radiation which is poisonous.
so called "dirty bombs" cannot be built and stockpiled like nuclear weapons can. they must be assembled shortly before use. a "dirty bomb" is simply a conventional bomb wrapped in radioactive waste, the detonation of the conventional bomb scatters the radioactive waste thus making it "dirty". the problem with making a "dirty bomb" is that radiation from the radioactive waste will almost certainly kill anyone involved in the assembly of the bomb. countries are very unlikely to seriously consider making such bombs, only terrorist groups are likely to attempt it.
Fusion (thermonuclear) bombs can be classified into 'dirty' and 'clean' bombs, depending on the material used for their fusion stage(s) tamper. Normally depleted uranium is used, this produces a very high yield 'dirty' bomb as the uranium fissions providing as much as 90% of the yield and large amounts of fallout. If you are willing to sacrifice most of the weapon's potential yield (but the yield is still very high), you can replace the fusion stage(s) tamper with non-fissionable metals (e.g. lead, tungsten, iron) and get what is called a 'clean' bomb that in some cases produces 5% or less of the fallout of similar yield bombs with uranium tampers. There are also bombs called 'salted' bombs where selected elements are added to the uranium tamper to make the fallout worse at a minor loss in yield depending on how much of these elements are added. Sometimes these are referred to as 'dirty' fusion bombs, when the standard uranium tamper bomb is referred to as a 'conventional' fusion bomb.
Easily obtained conventional explosives. This disperses the radioisotopes. (No nuclear explosion occurs)
A dirty nuclear bomb is detonated by using a conventional explosive. It disperses a large amount of nuclear material across the area.
because it dirty
Hydrogen bombs are called "dirty" bombs because, in the final stage of detonation, they fission1 a lot of uranium, releasing its binding energy. This results in a lot of mixed fission byproducts that contaminate the environment. -------------------------------------------------------------------- 1The detonation sequence is fission of the primary, uranium or plutonium, which initiates fusion, hydrogen, producing an enormous amount of neutrons along with radiation, followed by fission of the secondary or secondaries, uranium. For more information on the Teller-Ulam design, see the Related Link below.
The military are very aware of the risks of radiation both from nuclear explosions and also from "dirty bombs" that spread radioactive material. The NBC suit is the military's primary line of protection.
dirty bombs, as in the non-nuclear form, is simple: you take any type of potently radioactive material and some explosives, like C-4, and load them into a bookbag, a truck, anything, then go VERY far away and denote the explosives. the blast wave propels the radioactive material in a large dust cloud, and the dirty bomb has done its toll.
A "dirty bomb", a type of radiological weapon, can disseminate radioactive materials by means of a conventional explosion. Dirty bombs are potential terrorist weapons since advanced knowledge of physics and actinide chemistry are not needed to construct such a weapon.
