An initiating element (5) for use in a detonator (1) to cause a base charge (2), arranged in the detonator, to detonate comprises; an ignitable initiating charge (9, 10), which upon ignition generates combustion gases by means of which the base charge is intended to detonate, and a compression means (7), which is arranged to be moved towards the base charge by said combustion gases for compression of the base charge. The base charge is compressed during an initiation phase to increased density and is such that at a moment of detonation has increased density. |
