Analyzing Exposures to Electromagnetic Fields in an Intensive Care Unit

Area of Science:

• Medical Physics
• Environmental Health

Background:

• Intensive care units (ICUs) are critical healthcare areas with potential for high electromagnetic field (EMF) exposure.
• Assessing EMF levels in Turkish ICUs is crucial for patient and staff safety.

Purpose of the Study:

• To numerically analyze electromagnetic field (EMF) exposure in a hospital's intensive care unit (ICU).
• To establish baseline EMF measurements in Turkish ICUs and healthcare services.

Main Methods:

• Utilized a SRM-3006 selective radiation meter to measure high-frequency EMFs (47 MHz to 2.5 GHz).
• Collected 5929 observations at measurement points representing maximal potential exposure.
• Measured magnetic fields in V/m to assess absolute and limit values.

Main Results:

• No measurements exceeded the referenced maximum safety limits for EMF exposure.
• Mobile telecommunication devices were identified as the most significant contributors to magnetic fields.
• Measurements covered 17 frequency ranges within the tested spectrum.

Conclusions:

• While current EMF levels in the ICU did not exceed safety limits, mobile telecommunication poses a critical risk.
• Further research using diverse frequency antennas is necessary for comprehensive EMF assessment in ICUs.
