Radiation is like air, water, and soil. It is always around us. Except for pregnant women who are very sensitive to it, many people do not have enough awareness and protective measures. The 311 earthquake in Japan made Japan a "macro-nuclear nation." China became a "salt-child", and "radiation" became a word that panicked people after SARS and swine flu. The "anti-radiation" items that came with it became New buying products.
The micro-nuclear radiation that floats in Japan is compared with the radiation (mainly electromagnetic radiation) in our daily life. Just like sesame seeds and watermelons, we don’t “lost watermelons and sesame seedsâ€. The real radiation products are on our side. Pregnant women are more sensitive to radiation and their sensitivity, especially to business people who go to offices every day, go out for a car, and stand by their iPhone.
Radiation's greatest harm to current business people is sub-health: long-term radiation in the environment, can mainly cause dysfunction of the central nervous system and the mental system, mainly manifested as dizziness, fatigue, memory loss, loss of appetite, insomnia, forgetfulness, etc. Health symptoms.
With the increasing popularity of automobiles, automobiles have become a tool for urban people to travel. However, compared with mobile phones and home appliances, radiation is more severe and the in-vehicle penetration rate is higher due to the relatively narrow car environment and inconvenient ventilation. To reach 70% of navigation products, the amount of radiation can not be ignored.
The main reasons for radiation are the following:
1, vehicle-mounted GPS must be able to achieve the positioning of the body to achieve the user's navigation needs by receiving satellite signals, so the vehicle-mounted GPS as a car consumer electronics products in the normal use of the body must have electromagnetic radiation.
2, compared with ordinary household appliances, navigation DVD products in the working environment is very harsh, closed, small environment, large shocks, heat is very difficult, if the product in the early design focus on the issue of radiation, you can reduce the energy reflection and Overshoot, which dissipates a portion of the energy through heat, reducing the amount of energy that is radiated into space.
3, cross-radiation, in the car, navigation DVD products, mobile phones and other products from the owner is very close, the electromagnetic waves between different electronic products will interfere with each other, electrical appliances are placed together, will cause excessive dose radiation, in the closed car It is more likely to cause danger.
In February 2010, the General Administration of Quality Supervision, Inspection and Quarantine announced the 4th batch of national quality supervision and inspection notices for product quality in 2009. Of the 49 car navigation products sampled, 17 products were unqualified, and the failure rate exceeded 30%. The main reasons for the qualification are excessive radiation disturbances and excessive power terminal disturbance voltage.
Irrespective of whether the radiation disturbance exceeds the standard or if the power terminal's disturbance voltage exceeds the limit, there is a great danger. When the car GPS navigation is used, if the radiation disturbance exceeds the standard or the power terminal disturbance voltage exceeds the standard, the normal use of other electronic products in the vehicle will be seriously affected. Electronic devices such as mobile phones and Bluetooth headsets carried by other passengers in the car may also be affected. In severe cases, it may also cause problems with the automotive system and accidents. It is dangerous to assume that the patient's life in the vehicle maintains electronic equipment. “
In today's national radiation protection, choosing a product with low radiation is the main focus of the vehicle. The Junda brand of a good helper fully complies with national standards. These are the objects that everyone can consider.
The Junda brand enjoys the title of “the most cost-effective product†with its high quality and low price features. The Good Helper Group has been established for more than 13 years and has strong backgrounds and has undergone many years of market tests, both in consumers and dealers. There is a reputation, big brands are trustworthy.
At the just-concluded "2010 China Automotive Electronics Top Ten Selection Awards" ceremony, the Junda brand won the "Best Value Product".
