What is "alazan"

The Alazan rocket was a Cold War-era, 82mm Soviet rocket originally developed to distribute cloud-seeding chemicals such as potassium or silver iodide. Some were converted into improvised munitions and modified to carry explosive warheads. Others were retrofitted with a warhead reputed to contain up to 400g of radioactive caesium-137 and strontium-90, to help scientists track clouds and other meteorological events. Both types were acquired by militants following the Soviet collapse.
