Table AL3 - ALs for exposure to electromagnetic fields from 100 kHz to 300 GHz
| Frequency Range | External electric field strength ALs (E) [Vm-1] | Magnetic flux density ALs (B) [µT] | Power density AL (S) [Wm–2] |
|---|---|---|---|
| 100 kHz ≤ f < 1 MHz | 6.1 × 102 | 2.0 × 106/f | - |
| 1 ≤ f < 10 MHz | 6.1 × 108/f | 2.0 × 106/f | - |
| 10 ≤ f < 400 MHz | 61 | 0.2 | - |
| 400 MHz ≤ f < 2 GHz | 3 × 10-3 f1/2 | 1.0 × 10-5 f1/2 | - |
| 2 ≤ f < 6 GHz | 1.4 × 102 | 4.5 × 10-1 | - |
| 6 ≤ f ≤ 300 GHz | 1.4 × 102 | 4.5 × 10-1 | 50 |
| Exposure levels not exceeding the ALs will be compliant with: | Up to 6 GHz: the health effect ELVs in Table ELV4 6 – 300 GHz: the health effect ELV in Table ELV6 | The health effect ELV in Table ELV6 | |
Table AL4 – AL for exposure to electromagnetic fields from 10 to 110MHz
| Frequency range | Limb current AL (IL) [mA] |
|---|---|
| 10 ≤ f ≤ 110 MHz | 100 |
| Exposure levels not exceeding the ALs will be compliant with: | The health effect ELV in Table ELV4 - localised SAR in the limbs |
