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 |
1. The electric field strength and magnetic flux density ALs are root mean square values.
2. For radiofrequency pulses, the peak power density averaged over the pulse width must not exceed 1000 times the respective AL (S) value. For multi-frequency fields, the analysis must be based on summation.
3. Note 3 to Table AL1 applies in relation to the ALs for external electric field strength and magnetic flux density.
4. The power density is the maximum level averaged over any 20cm2 of exposed area. Spatial maximum power densities averaged over 1cm2 must not exceed 20 times the value of 50 Wm-2.
5. From 6 to 10 GHz, power density must be averaged over a six minute period. Above 10 GHz, it must be averaged over a 68/f1.05-minute period (where “f” is the frequency in GHz).
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 |
The AL is a root mean square value.

Explanatory Memorandum sets out a brief statement of the purpose of a Statutory Instrument and provides information about its policy objective and policy implications. They aim to make the Statutory Instrument accessible to readers who are not legally qualified and accompany any Statutory Instrument or Draft Statutory Instrument laid before Parliament from June 2004 onwards.

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:
