PART 3Indirect effects of exposure

Action levels – non-thermal effects

Table AL5 - ALs for contact currents

Frequency of electromagnetic field in which an object is present

Contact current ALs (Ic)[mA]

up to 2.5 kHz

1.0

2.5 ≤ f < 100 kHz

0.4 f

100 ≤ f ≤ 10,000 kHz

40

NOTES

1

“f” is the frequency expressed in kHz.

2

The ALs are root mean square values.

3

The ALs represent the maximum steady state current created during a continuous contact with an object in an electromagnetic field.

Table AL6 – ALs for static magnetic fields

Potential indirect effect

Magnetic flux density ALs (B0)[mT]

Interference with active implanted medical devices

0.5

Attraction and projectile risk in the fringe field of high field strength sources (> 100 mT)

3

NOTE

The AL for interference with active implanted medical devices represents the maximum field value at any place where a worker may be working.

NOTES

1

The AL is a root mean square value.
