适用范围：This document is concerned with the fact that an electric blasting cap (initiator) might explode unexpectedlywhen a nearby radio transmitter is turned on. A cap can absorb electrical energy from a free-spaceelectromagnetic field of the type produced by radio and radar transmitters. This document providesrecommendations for limiting the amount of electrical energy absorbed and recommended methods fordetermining safe distances from radio and radar transmitting antennas when one is using electric blasting caps.Safety is determined by comparing the RF power pickup to the blasting cap’s no-fire power level. Thiscriterion is valid over the frequency range 3 kHz to 300 GHz that is commonly discussed in connection withRF safety. Radio frequency transmitters that a blaster might encounter occupy only a small portion of thisfrequency range. Specifically, this document explains how to determine safe distances from RF transmitterswith spectrum bands from 10 kHz to 12 GHz, including VHF and UHF television antennas, FM and AM radiotransmitting antennas, radar, navigation beacons, and portable communication devices.This document excludes criteria for the use of electro-explosive devices (EEDs) with electrically conductiveenclosures or weapons containers, and it does not include sufficient information on hazards deriving fromelectrostatics or from electromagnetic fields generated by other sources of energy, such as electrical storms,electromechanical equipment, electrical power plants, or power transmission lines. This document does notapply to the use of non-electric detonators.
