unit.

EMF may also disrupt the operation of medical implants (materials placed inside the body), such

as pacemakers. Protective measures should be taken for people who carry medical implants. For

example, access limitation may be imposed for passers-by, or individual risk assessments may be

conducted for welders. Risk assessment should be conducted and recommendations should be

made by a medical professional for users who carry medical implants.
