The highest Radiation of Household Appliances

When it comes to the safety of the use of household appliances, many people are always a bit worried, not only because of the use of individual appliances easily lead to improper explosion, but also because that household electrical appliances have a detrimental to the health of the common — produce radiation. Radiation household appliances not only induce gene mutation, promote the variation cell production, accelerate the skin aging, but also disrupt hormone secretion, affect the central nervous system, resulting in neurasthenia.

In view of the different categories of household electrical appliances are not the same value of radiation, the following is a different level of household electrical appliances radiation list.


Microwave oven

The maximum radiation is near the door,especially at the moment you open the door , so it is not too close to it when it is working as the radiation range of up to 7 meters.

Electric blanket

The blanket power will generate electromagnetic fields, the generated electromagnetic radiation. Pregnant mammy if use electric blanket, a long time in the electromagnetic radiation, most likely to cause fetal brain, nervous, skeletal and heart tissues by adverse effects.


Almost of us love Humidifier, but we all don’t know the radiation of it is so big,therefore, when in use do not put in place too close from the body.

Fat motor

The transmission belt front radiation is bigger, the movement time should not be too long, as far as possible reduces the radiation.

Hair dryer

Although small in size, but radiation is great, should be kept away from children. The opening and closing of the hair dryer, as far as possible from the head far a little, when in use, the best hair dryer and keep the head in vertical, not for a long time use best intermittent stop.

Electromagnetic oven

Now more and more families like to use the cooker to cook things, but should pay attention to the use of time not too long.

What Are Nitrates and Nitrites?

Nitrates are mainly produced for use in agriculture as fertilizers. The main nitrates are potassium, calcium, sodium, and ammonia salts. Nitrates are also fast oxidizing agents and because of this they are used in creating explosives. Sodium nitrite is the most common nitrite used for curing meat because it discourages bacterial growth. Sodium nitrite is actually the chemical responsible for giving cured meat its pinkish look.

Nitrates and nitrites have been linked to cardiovascular disease as well as cancer in the literature. As a result, many people vilify cured meats and processed meats – including our beloved bacon. But do you know where the majority of your nitrates and nitrites come from? Approximately 80% of ingested nitrites and nitrates come from fruits and vegetables.

Aren’t fruits and vegetables good for us? You bet they are, and believe it or not it, that may be due to some of the physiological effects of nitrates. The beneficial effects of nitrates and nitrates may include lowered blood pressure, decreased oxidation, improved immune system function, and neurotransmission. This is mainly due to the conversion of salivary nitrates into nitric oxide, as the majority of nitrates are found in human saliva.

In addition, researchers were able to identify the protein sialin as a nitrate transporter. Not only is sialin shown in salivary glands, but also the heart, lungs, kidneys, and brain.2 This shows that nitrates and their conversion to nitric oxide may play an important role in the health of a number of our organs.


What should we do to avoid adding to much nitrate

As we know from the above, most of nitrate are come from fruits and vegetables. Some vegetables due to the unhealthy grow, they may in high level of nitrate, and if the fruits and vegetables are not fresh, they are in higher nitrate level. So it is very important to choose the fresh vegetable and fruits.

When picking up vegetables and fruits, some nitrate detetor can help you check the level before buying them. Some kinds of vegetables are in high level of nitrate. With this tool, you can easily know wether the food your are buying are healthy or not.

What’s more, some kinds of vegetables are high in pesticides, in other words, those vegetables that are in high pesticides may contain higher nitrate than normal. So it is quite important to wash your vegetables and fruits throughly before cooking, you can learn more about Harm of Pesticide Residue and its Detection Method.

The Relationship Between the Vegetable & Fruit Freshness and Nitrite Content

We know that fruits and vegetables contain nitrate. The nitrate in fruits and vegetables mainly from artificial fertilizers such as ammonium nitrate, calcium nitrate, potassium nitrate, sodium nitrate and urea nitrogen in fertilizer by soil transfer.

Fruits and vegetables after nitrogen absorption, often to nitrate are temporarily stored in the body. Inorganic compounds in leafy vegetables such as spinach, celery, cabbage, Chinese cabbage, cabbage, lettuce, leeks, sugar beet, cauliflower, radish leaves, Chenopodium album, shepherd’s purse and other, but the content is rare. General fresh edible had no effect.


However, if the vegetables are not fresh, nitrate will be converted to nitrite in plants, resulting in a significant increase in the content of nitrite.

Short time in eating a lot of vegetables, a lot of nitrate into the intestinal tract, intestinal bacteria the conversion of nitrate to nitrite, in the intestine too much too quickly formed that late decomposition, a large number of nitrite into the blood will cause poisoning. Just pickled vegetables contain a large number of nitrite, 7-8 days reached the peak, 15 days decreased, 20 days after the disappearance. In order to avoid corruption and nitrite content, fresh fruits and vegetables is best not to long-term preservation, storage should be low temperature storage, such as frozen. Pickled vegetables to 15 days after edible.

Nitrite is toxic, in the food processing industry is most common is sodium nitrite. Very similar to the properties of sodium nitrite with our daily consumption of salt is often used as food additive coloration and antiseptic effect, widely used in meat, sausages and canned meat food. In fruits and vegetables in order to reduce the conversion of nitrate to nitrite content we suggest as far as possible the selection of fresh fruits and vegetables.

How to judge the fruits and vegetables are fresh? We usually choose the morning to buy fruits and vegetables, because the fruits and vegetables just listed, a relatively new; secondly, the most used method is observed, inspect the vegetable leaves will not yellow, rotten leaves.Fresh vegetable Chui brilliant and root fertilizer with straight is preferred.

In addition, you can also use nitrate detector to test nitrate content in vegetables and fruits determine whether they are fresh. nitrate test kit can help you test the nitrate and pesticides in your fruits and vegetables thus  you can control the too much harmful substance intake to your body.
