The major causes of radio frequency radiation hazards are the transmitting antennas of radio, TV, radar, cell phones, wireless data acquisition systems and global positioning systems in the new age of communication technology using various modulation schemes such as amplitude modulation (AM), frequency modulation (FM) etc. The transmitting antennas of these communication devices generate electromagnetic fields (EMFs). Under such conditions, electric detonator wires work as receiving antenna and pickup sufficient energy from electromagnetic fields to initiate an accidental explosion. There have been several instances of accidental firing of detonators by radio frequency pickup. In this study an attempt has been made to minimize such explosions and to provide a basis for the assessment and simulation of the radio frequency radiation hazard parameters associated with industrial electric detonators. This research examines the radiated powers of various frequency bands to determine the safe distance from transmitting antenna. Two empirical relationships for the estimation of minimum safe distance (MSD) have been suggested based on mathematical simulation. Using these relations desired MSDs have been calculated for the relevant frequency bands. The values obtained have been compared with the experimental values available that demonstrated strong agreement between them. The average percentage deviations of calculated MSDs from suggested relations are found between 0.096% and 10.718%, with regression coefficient 0.970 ≤ R ≤ 1. This reflects the soundness of the proposed empirical relations. The blasting engineers, detonator designers and researchers may use these relations as a handy tool to prevent undesired explosions by maintaining minimum safe distance in radio frequency prone hazardous areas.

工业用雷管在射频辐射危险中的安全使用的经验建模和评估方法

射频辐射危害的主要原因是在通信技术新时代中使用各种调制方案（例如幅度调制（AM），频率）的无线电，电视，雷达，手机，无线数据采集系统和全球定位系统的发射天线这些通信设备的发射天线会产生电磁场（EMF）。在这种情况下，电雷管导线用作接收天线，并从电磁场中吸收足够的能量以引发意外爆炸。有几种情况是射频拾取意外引爆雷管。在这项研究中，已尝试将此类爆炸减至最少，并为评估和模拟与工业电雷管相关的射频辐射危险参数提供基础。这项研究检查了各个频带的辐射功率，以确定与发射天线的安全距离。在数学模拟的基础上，提出了两个经验关系，用于估计最小安全距离（MSD）。利用这些关系，已经为相关频带计算了所需的MSD。将获得的值与可用的实验值进行比较，这些实验值证明了它们之间的强烈一致性。计算得出的MSD与建议关系的平均百分比偏差为0.096％至10.718％，回归系数为0.970≤R≤1。这反映了所提出的经验关系的合理性。爆破工程师，雷管设计人员和研究人员可以使用这些关系作为方便的工具，通过在易发生射频的危险区域中保持最小安全距离来防止意外爆炸。
