Distance and Location of Both Mobile Phones and Health Care Units: Determines the Interference Level

Abstract

60 Million mobile phone holders in the country forces clinics and cellular phones have been started to be in concern as an electromagnetic interference (EMI) source in hospitals. Hospital buildings are very huge buildings that they are not allowing deep radio penetration through the hole those results in higher uplink power transmission (2W of maximum). These two reasons were our motivation to make an investigation to examine the EMI issues surrounding medical equipment, due to interference from communication devices, including GSM900, GSM1800, and 3G digital mobile phones. Electromagnetic interference, particularly of the ECG and ted EEG device was observed, and exposure begins within the range of 1.25m. It has been observed that uplink power is not a reason of interference itself, but the locations of mobiles and health care units are also the reason of interference.

ELISA reader does not interfere by mobile phone radiofrequency radiation

“…Moreover, regarding the serum analytical equipment, there was only evidence that the RF radiation does not affect these devices at a far distance (1.4 m). [ 2 ] In medical laboratory for serum analysis, ELISA readers are widely used as a useful diagnostic tool for Enzymun colorimetric reading. In this experiment, we aimed to investigate whether ELISA reader could be interfered by the closed contact (less than 5 cm distance) exposure to the 900 MHz cell phones in the laboratory.…”

“…Recently, Helhel et al ., found that mobile phone usage, 1.4 m farther than the serum analytical equipments does not cause EMI. [ 2 ] However, some equipment such as electrocardiograms (ECGs) are susceptible to mobile phones EMI at a closer distance (less than 0.4 m). However, the critical distance is not a concern itself, but also the location and orientation of both sources and medical equipments are important as mentioned in ANSI C63.18.…”

“…The aim of this study was to investigate whether the ELISA reader could be interfered by the exposure to the 900 MHz cell phones in the laboratory. At present, there is only evidence that the RF radiation does not affect the serum analytical equipment at a far distance (1.4 m),[ 2 ] while, according to the best of our knowledge, there is no data for the closed contact with the methodology and analysis described here.…”

“…Electromagnetic interference (EMI) due to radiofrequency (RF) radiation from external sources such as cellular telephone, radio communication, computer, radar, and antennas in medical environments is being widely studied by several authors. [ 1 2 3 4 5 6 ] Beside the beneficial characteristics of these devices, the user also have to pay attention to the different sources of EMI in medical environments and particularly the use of a mobile phone inside medical facilities as the most typical situation.…”

Hazard estimation from Radiofrequency Radiation in a Nigerian Teaching Hospital from nearby GSM Base-Stations

“…The study area was chosen for this study more particularly to provide a baseline data for radiofrequency exposure in the study area. Although radiofrequency interference (RFI) has been observed in some medical device in close proximity with cell phone [20,21], a look at the level of radiofrequency field emanating from base stations and estimation of its potential hazard may also be useful for future studies.…”
