Final answer:
Nonel caps can be used to initiate many cap-sensitive explosives. TNT, characterized by its insensitivity to shock and friction, requires a high velocity initiator and has an F of I rating of 100, while RDX, more sensitive, has an F of I rating of 80.
Step-by-step explanation:
The question asks whether a "Nonel" cap can detonate all types of explosives that are cap sensitive. A Nonel cap, also known as a non-electric detonator, can be used to initiate the detonation of many cap-sensitive explosives. However, whether a specific type of cap-sensitive explosive can be detonated by a Nonel cap depends on the physical properties and sensitivities of the explosive compound in question.
For TNT, it requires a high velocity initiator or efficient concussion to be detonated. On the "Figure of Insensitivity" (F of I) scale, TNT had a rating of 100, indicating its relative insensitivity compared to other explosives. This value means that TNT has a reduced risk of accidental detonation because it is less sensitive to shock and friction. However, to detonate TNT, it must be triggered by a pressure wave from an explosive booster.
RDX, a more sensitive explosive than TNT with an F of I rating of 80, is now used as the reference point for the F of I scale. As RDX is more sensitive than TNT, it will generally require a less strong initiating stimulus to detonate, making non-electric detonators like Nonel caps appropriate for initiation.
Therefore, while Nonel caps can be used with many explosives, it is essential to consider the specific characteristics of each explosive to determine whether it can be effectively detonated by a Nonel cap. It is the responsibility of professionals in the field to assess each situation and choose the appropriate initiation method.
