räjäytin

Räjäytin is a Finnish term that translates to "detonator" or "blasting cap" in English. It refers to a small explosive device used to initiate the explosion of a larger explosive charge. Detonators are crucial components in various blasting operations, including mining, construction, and demolition. They provide a reliable and controlled method for igniting explosives, ensuring safety and efficiency.

There are several types of detonators, broadly categorized into electric and non-electric. Electric detonators utilize an electrical current to trigger a small heating element, which in turn ignites a pyrotechnic delay element and then the base charge. Non-electric detonators, such as those using detonating cord or shock tube, transmit the initiation signal through a physical pathway. The choice of detonator depends on factors like the required delay time, the type of explosive being used, and safety considerations for the specific application.

The use of räjäytin requires specialized knowledge and adherence to strict safety protocols. Improper handling or use can lead to premature detonation, causing severe injury or death. Regulations govern the manufacture, storage, transportation, and use of detonators to minimize risks. They are essential tools for controlled explosive events, enabling tasks that would otherwise be impossible or extremely hazardous.
