Description
Protection against electromagnetic radiation from induction hobs !
Induction hobs generate electromagnetic fields. These are low or medium frequencies that oscillate between 20 and 100 kHz.
Our shielded apron is equipped with two shielding foils. These magnetic field shielding foils for the chest and stomach area are attached to the inside of the apron.
The foil made of nanocrystalline soft magnetic metal with high magnetic permeability is ultra-thin, light and flexible. It reduces the low-frequency magnetic field (nT) generated by IH cooking appliances by up to 80 %.
It is possible to double the shielding foil or replace it with an optional foil.
The kitchen apron is made of high-quality cotton fabric that is impregnated with a stain protection agent, making it impermeable to water, oil and vapour.
The kitchen apron is made of high-quality, stain-resistant cotton canvas and is therefore water, oil and vapour repellent.
The apron is the perfect outfit for the kitchen: it protects clothing and has practical loops and pockets. It is pre-washed and therefore does not discolour or fade in the washing machine.
Only the denim apron needs to be washed separately!
Care instructions: Before washing, be sure to remove the shielding film from the kitchen apron.

Cooker with induction hob
In contrast to cooking with gas or conventional glass ceramic hobs, the heat is not generated by heating elements in the hob or by the flame, but directly in the base of the pan. There is an induction coil under the glass lid, which is supplied with high-frequency alternating current.
This creates an alternating magnetic field. In a magnetisable pot on the hob, eddy currents form in the base of the pot. This then heats up and transfers the heat to the contents. While conventional electric cookers are operated with 50 Hz alternating current, the frequency of the magnetic field in induction cookers can be up to around 1000 times higher.
According to the International Commission on Non-Ionising Radiation Protection (ICNIRP), induction hobs must not exceed a magnetic reference radiation of 6.25 microtesla (µT) / 6,250 nanotesla [nT] at a distance of 30 cm from the hob if only one hob is used (provided there is a sufficiently large pot on this hob).
To reduce the risk of radiation from induction hobs during use, it is advisable to follow the advice below:
– Only use pans that are suitable for induction cooking.
– Do not use damaged pans with a dented or curved base.
– Use a pot that completely covers the hob: Do not use pots that are too small and place the pots in the centre of the cooking zone.
– If possible, use the hotplates at the back.
– Keep a distance of at least 5-10 cm, preferably 30 cm, from the hotplates. This applies in particular to pregnant women and small children.
– Do not use metal spoons while cooking to prevent radiation from escaping into the body.
– People with a pacemaker should discuss with their doctor whether they are allowed to use induction hobs. The British Heart Foundation
(BHF) advises people with a pacemaker to keep at least 60 cm away from induction hobs.
Worth knowing: Not only induction cookers generate very high alternating magnetic fields in the kitchen.
Here are some examples of measurements on various electrical appliances at a distance of approx. 20 cm
Toaster 200 nT
Electric kettle 200 nT
Electric cooker at full power approx. 200 nT.
Oven set to 200°C 1000 nT
Induction cooker at full power approx. 2500 nT
Microwave oven more than 6000 nT
