Dirty Bomb padha kyaa?

Shashank Sachi 5 MINUTES

Why in news: In Russia’s latest advocacy campaign over its invasion of Ukraine, Moscow has focused on accusations that Kyiv might be planning to use a so-called “dirty bomb” – a conventional explosive device laced with toxic nuclear material.

Dirty Bomb: 

  • It is a bomb that contains radioactive material, such as uranium, which is scattered through the air when its conventional explosive detonates.
  • It doesn't need to contain highly refined radioactive material, as is used in a nuclear bomb. Instead, it could use radioactive materials from hospitals, nuclear power stations or research laboratories.
  • This makes them much cheaper and quicker to make than nuclear weapons. They can also be carried in the back of a vehicle.
  • However, as weapons, they are very unreliable.
  • For the radioactive material in a dirty bomb to be scattered across its target zone, it has to be reduced to powder form.
  • But if the particles are too fine or released into strong winds, they will scatter too widely to do much harm.

Material used:

  • Cesium-137
  • Cobalt-60
  • Iridium-192
  • Dynamite
