| تقنيات التخفيف للحد من تعرض الإنسان للمجالات الكهرمغنطيسية بالقرب من محطات الاتصالات الراديوية |
تحدد التوصية ITU-T K.70 التقنيات التي يمكن لمشغلي الاتصالات استخدامها لتقييم نسبة التعرض التراكمي (الكلي) على مقربة من هوائيات الإرسال ولتحديد المصدر الرئيسي للإشعاع. وهي تقدم إرشادات بشأن أساليب التخفيف التي تسمح بتخفيض مستوى الإشعاع من أجل الامتثال لحدود التعرض. وهي توفر الإرشاد أيضاً بشأن الإجراءات اللازمة في البيئة (على أرض الواقع) التي يحدث فيها، في معظم الحالات، تعرض في وقت واحد لترددات متعددة من عدة مصادر مختلفة. وقد تعود مصادر الإشعاع إلى العديد من المشغلين وقد تمثل خدمات الاتصالات الراديوية المختلفة (من قبيل، الأنظمة الخلوية، وأنظمة الكبلات، والبث الإذاعي، والمرحلات الراديوية، والنفاذ اللاسلكي، وما إلى ذلك). |

| Observation: | This Recommendation contains a software EMF-estimator that implements the methodology described in ITU-T K.70, and gives the possibility to calculate the cumulative exposure for the reference levels. It also contains the library of the radiation patterns of transmitting antennas for a wide range of radiocommunication and broadcast services. The EMF-estimator is not appropriate for the equipment certification in order to put it on the market.
A new version v2.0.0 of EMF estimator is available in ITU-T K.70 (2007) Amend.2 (2011-05). |
