Lithium-220 does not exist.
Lithium is a very light element, It only occurs naturally as Lithium-6 and Lithium-7, which are both stable. All other isotopes have halflives shorter than one second, and thus would decay too fast to be usable in anything.
We'll consider "dirty" to mean producing radioactive fallout. Since hydrogen bombs (fusion bomb) require the energy from an atomic bomb (fission bomb) they are a little dirty. Its mostly the atomic bomb that creates dangerous isotopes that contaminate the blast area, and regions down-wind. Now an H-bomb is generally "cleaner" than a bomb purposefully-design to create a large amount of dangerous, radioactive fallout. There are various techniques where one can change the type and duration of fallout. These types of weapons are generally use fission (not fusion) to create this effect.
The term 'dirty' bomb - refers to a device that is contaminated with either radiation or pathogens. When the device explodes, it spreads the contamination over a wide area. It can be as simple as a grenade that's been exposed to radiation.
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
There are two types of bombs that are referred to as "dirty" bombs:A dirty conventional bomb or more precisely a radiological bomb. This is simply a conventional chemical explosive bomb wrapped in highly radioactive isotopes. It will likely kill everyone involved in assembling and delivering it before it can hurt anyone at its target.A dirty hydrogen bomb or more precisely an enhanced fallout nuclear bomb. This is a hydrogen bomb with its depleted uranium tamper replaced by or "salted" with other elements that absorb neutrons strongly and transmute into highly radioactive isotopes, producing much more fallout that is more deadly. Cobalt is commonly referred to in the popular literature but would not actually work well as its capture cross section for high energy fusion neutrons is rather small. Gold would be ideal from a military standpoint as its capture cross section for high energy fusion neutrons is large and the halflife of the radioisotopes produced is short enough to allow occupation of the affected territory within a few months (however gold is too expensive for this use).
Initial report are that flash powder removed from fireworks was used to build the bomb.
Pretty much any radioactive material can be used.

No, a dirty bomb is a radiological weapon. It simply uses conventional explosives to scatter radioisotopes over an area.

A dirty nuclear bomb is detonated by using a conventional explosive. It disperses a large amount of nuclear material across the area.
is called a dirty bomb.
