The protection of man and his environment from undue exposure from radio frequency electromagnetic field requires identification of the location where exposures are likely to be higher than safe levels established by international safety standards. A wideband measurement with a spectrum analyzer and a log-periodic antenna in conjunction with the three-point spatial average method was used. The results ranged from 16.21 to 2907.00 mVm−1 and complied with a maximum of 1.08% of the ICNIRP reference level. Private frequency modulation (FM) sources were identified as the major source of exposure to the public with a mean value of 337.70 ± 133.70 mVm−1 against 122.30 ± 36.47 mVm−1 for the public FM transmitters. Even though the result was lower than a workplace assessment, it was, however, higher than similar works conducted in Africa and Palestine. Finally, four sensitive locations were identified for further research work.

加纳广播发射机的潜在暴露水平

保护人类及其环境免受射频电磁场的过度暴露需要识别暴露可能高于国际安全标准规定的安全水平的位置。使用频谱分析仪和对数周期天线以及三点空间平均法进行宽带测量。结果范围为 16.21 至 2907.00 mVm-1，最大符合 ICNIRP 参考水平的 1.08%。私人调频 (FM) 源被确定为公众暴露的主要来源，其平均值为 337.70 ± 133.70 mVm-1，而公共 FM 发射器的平均值为 122.30 ± 36.47 mVm-1。尽管结果低于工作场所评估，但高于在非洲和巴勒斯坦进行的类似工作。
