Abstract :
Nowadays, radio system transmitter (Tx) harmful interference and radiation effects are significantly important and complex. A very important issue is the requirement for coexistence of transmitters (Tx) and receivers (Rx) on the same site (cosited), where radio mutual interference and radiation hazards are significantly more important than from internal, natural and industrial noise effects. Results show that under some cosited scenarios when victim Rx are blocked or strongly desensitized by high power interfering Tx. Persons located in the proximity of the Rx may be affected by radiation intensity which may approach the standard threshold limits. Thus, we can conclude that in special cases, described in this paper, a correlation exists between Tx´s interference to victim Rx and radiation intensity level to exposed human. However it is important to emphasize that the sensitivity of Rx to Tx high power interference is significantly higher than the sensitivity of exposed people to radiation effects.
