- healthy cooking, no fat used, no loss of vitamins
- energy saving, no pre-heating, time-saving speed
- quick and problem free defrosting
- less washing up, foot cooked in the serving dish
- easy to clean
- easy to use

Frequency

The frequencies are determined by the number of current oscillations resp. of the
electromagnetic waves per second.

Classification of Frequency Bands:

3 - 30 KHz
30 - 300 KHz
300 - 3000 KHz
3 - 30 MHz
30 - 300 MHz
300 - 3000 MHz
3 - 30 GHz
Transmitting frequencies and microwave frequencies in the UHF range are fixed by
international agreements.
To avoid any influences and interferences,
the microwave frequency is fixed to:

Radiation Spectrum

ionizing – nonionizing
The different frequency
bands are divided into
ionizing and nonionizing
frequencies
- VLF
- Very low frequency - Telephone
- LF
- Low frequency - Ultrasonics
- MF
- Frequency modulation - Radio
- HF
- High frequency - Radio, Broadcast
- VHF
- Very high frequency - TV, Broadcast
- UHF
- Ultra high frequency - Radar, Microwaves
- SHF
- Super high frequency - Satellite Transmissions
created by TSE-N, Reiner Kurzke
2450 MHz
Microwaves are in the
nonionizing range.
They therefore also do not
have anything to do with
radioactivity.
Radioactivity can only
occur with essentially
higher frequencies.
The microwave effect only
influences a heating of
water molecules which,
whatever capacity is
affecting, does not exceed
100°C.
