8 strokes to reduce electrical radiation
Electrical appliances can emit electromagnetic radiation as long as they are connected to the power supply. This includes air conditioners, televisions, computers, microwave ovens, hair dryers, mobile phones, chargers, and cables. Because of this, electromagnetic radiation is often referred to as the "invisible killer," and many people are concerned about its potential effects on health. But how much radiation do these devices really produce, and is it dangerous?
Let’s take a closer look at some common household appliances:
**Refrigerator:** The back or bottom of the refrigerator contains a heat-dissipating pipe that emits a magnetic field. This field can be tens or even hundreds of times stronger than the front. For example, while the front may measure 1-9 mG, the center of the back could reach up to 300 mG. If dust accumulates on the pipe, it can increase the refrigerator’s power consumption and intensify the magnetic field. Regular cleaning with a vacuum cleaner can help reduce the exposure.
**Computer:** LCD monitors generally emit less radiation compared to older CRT models. However, if your desk is too small and you’re forced to sit close to the screen, try moving the monitor further away. Switching to an LCD monitor significantly reduces radiation. As for the computer tower, it's often overlooked but can emit strong magnetic fields—up to 4 mG in front, and even more at the back.
**Mobile Phone Charger:** Most phone chargers use a transformer, which can generate a high magnetic field near the plug. At the point where the cable connects, it might measure over 300 mG, but this drops below 1 mG after just 30 cm. So, keeping a safe distance from the charger is advisable.
**Microwave Oven:** Even when not in use, some microwave ovens still emit a noticeable magnetic field, especially on the front panel (around 30–60 mG). When in operation, the field can exceed 200 mG. It’s important to avoid standing directly in front of it while it's running.
In our daily lives, we're constantly exposed to electromagnetic radiation. While it's unavoidable, there are ways to minimize the risks. Here are 8 practical tips to help reduce your exposure:
1. **Avoid clustering appliances:** Don’t place TVs, computers, or refrigerators together, especially in bedrooms. Keeping them separated helps reduce cumulative exposure.
2. **Stay away from the back of the computer:** The strongest radiation comes from the back of the monitor, followed by the sides. Try to position yourself in front of the screen.
3. **Limit standby mode:** Many devices still emit low levels of radiation when in standby. Avoid leaving them on for extended periods.
4. **Answer calls after a short delay:** Radiation is highest when a phone first connects or is charging. Wait a few seconds before answering, and avoid using it while it's charging.
5. **Use water to absorb radiation:** Water is an effective medium for absorbing electromagnetic waves. Place plastic or glass bottles of water around your computer, but never metal containers.
6. **Wash your hands and face:** Computer screens can accumulate static electricity and dust, which may transfer to your skin. Wash your face and hands after using the computer to avoid irritation or skin issues.
7. **Ensure good ventilation:** Computers can release harmful substances like brominated dibenzofuran. Keep the room well-ventilated, or use a fan if possible.
8. **Eat foods rich in antioxidants:** Consuming foods like carrots, oranges, tofu, and green leafy vegetables can help your body resist radiation. Drinking tea, which contains polyphenols, also supports protection against harmful effects.
By being mindful of how we use our devices, we can reduce our exposure to electromagnetic radiation and protect our health.
