Unfortunately these bombs neither stay in the condition they are in, nor improve - they become less and lesser stable, due to erosion. The experts say the risks are climbing, not stagnating or declining. That is true for both chemical and mechanical detonators.

If you ever visit the Baltic and here the place around island Rügen, be careful in case you see amber washed onto the beaches. It may not be amber, but phosphorus. Every year tourists get hurt by picking it up and it either goes up in flames in their hands, or in their pockets. The phosphorus stems from huge quantities of bombs dumped in the ocean and very close to the beaches. Fishermen have to live with the risk of picking it up in their nets. The stuff comes from bombs in the ocean whose hulls are collapsing and break open.
