Microwave - and other forms of electromagnetic - radiation are major (but conveniently disregarded, ignored, and overlooked) factors in many modern unexplained disease states. Insomnia, anxiety, vision problems, swollen lymph, headaches, extreme thirst, night sweats, fatigue, memory and concentration problems, muscle pain, weakened immunity, allergies, heart problems, and intestinal disturbances are all symptoms found in a disease process the Russians described in the 70's as Microwave Sickness.

This paper describes EMI with medical devices used in hospitals from mobile phones. Transmission power, frequency, transmission mode, and radiation sources are considered to investigate the relationship with EMI. LTE, HSPA, and W-CDMA are selected as the transmission method. Thirty-two different medical devices, which are mainly used in the operating room or ICU, are used in this evaluation. The results show that 12 medical-device models incurred EMI. The results also clearly show that the EMI strongly depends on the transmission power and the distance between the mobile phone and medical device. For example, when transmission power at 800 MHz is the nominal maximum and 10 dBm, the maximum EMI distances are approximately 70 and 10 cm, respectively. Based on this, the nominal maximum power test is important for conservative evaluation. On the other hand, the results do not show that EMI is dependent on the frequency band. Therefore, evaluations must consider all mobile phone frequency bands so that EMI can property detected. Furthermore, the electromagnetic field emitted by a half-wave dipole antenna causes higher levels of EMI than that by a mobile phone. Finally, we show that discontinuous transmission might cause higher levels of EMI than those for continuous transmission.
