Summary The major objective of the design of safe crowded transmitting antenna sites is not only to determine a safe zone around each
individual antenna; rather, to establish safety areas at the antenna site itself, as well as, at the neighboring areas. The
requirement is to ascertain the safety regions by considering the following parameters at each Test Point (TP) (or area segment):
the contribution of N co-located radiating antennas to the total radiation incident at the TP, the radiation pattern of each antenna, the near/far
field region of each antenna, and most importantly, the different Permissible Exposure Limits (PELs) associated with each
operating frequency at the antenna site. Implementation of all the above-mentioned aspects in a suitable computer requires
resources that only expert knowledgeable organizations possess. The graphically aided tool presented in this paper facilitates
the calculation of a “safety zone” for RADHAZ around a crowded antenna site from the knowledge of the “safety ranges” which
correspond to the individual transmitting antennas comprising it. 相似文献

The new recommendations of WHO and EC for legislation in Europe and other countries concerning non-ionizing radiation (NIR)
health and safety include exposure limits that are very debatable. ICNIRP Guidelines propose exposure limits for electromagnetic
fields in the frequency range up to 300 GHz based on short-term exposures and on thermal effects. The new EC proposal for
optical and laser safety legislation includes classification of sources of radiation—both lasers and other optical sources,
but not requirements for the methodology of classification. On the other hand, many new requirements have been set by the
WHO publication “Model Legislation for EMF Protection” concerning the responsibilities in the field of EMF health and safety.
Many specialists in the field of developing exposure limits have positions very far away from the proposed of the ICNIRP Guidelines
philosophy. The results are different approaches in developing standards and exposure limits, and differences more than 100
times in maximal permissible levels. We, the Bulgarian Program Committee on NIR, try to organize working groups and discuss
different philosophy for developing exposure limits for more than 10 years. This paper exposes our position in this area. 相似文献

The large number of radio frequency (RF) transmitters employed in modern marine platforms requires that they operate in mutual
coexistence while posing no danger to operators and equipment despite the limited available physical space. A key to the successful
system integration is the control of the electromagnetic environment on the ships’ topsides, which might pose radiation hazards
(RADHAZ) to personnel (HERP). HERP are caused by transmitter antenna installations that generate intentional EM radiation
in excess of the safe levels in zones of personnel activity. Radiation safety to personnel is achieved when the average radiation
power density is below the permissible exposure limits (PEL) for HERP at locations of personnel activity and medical equipment
operation. This paper describes the analysis tools and techniques for the evaluation of HERP on marine platforms. The same
approaches could be employed in the analysis of land site antenna deployment scenarios. 相似文献

首先通过理论分析了线缆在电场中产生的电流大小,其次使用带状线装置产生均匀场强,通过测量找出线缆感应电流与场强之间的传输函数关系,从而验证了BCI法与空间辐射场的等效性,这为将来我国汽车电子BCI法制定合适的试验限值提供了参考。 相似文献
