In addition to appearance and quality of computer case, it is also necessary to check whether it is radiation resistant!
When it comes to a computer case, almost all beginners might think that it is just a computer container. In fact, this is not necessary, main thing is that it looks good. But is chassis really such a product?
In fact, in eyes of some high-end players, chassis also has function of supporting air duct to accelerate heat dissipation, as well as anti-resonance and moisture-proof. However, in addition to these, chassis actually has a very important role, that is, radiation protection.
Emissions inside a computer mainly include ionizing radiation and electromagnetic radiation. Chassis material is generally lead-free galvanized steel, which absorbs radiation well. Of course, some chassis also feature a see-through design for aesthetics.
As for very transparent cases, most of them are made of acrylic material. Therefore, for such a chassis, there are often radiation-resistant shrapnels, that is, EMP shrapnels. It also absorbs radiation.
For ionizing radiation, short-term radiation that human body can perceive is about 100 millisieverts. Any excess will harm human body, and human body can withstand a maximum radiation of 1000 microsieverts per year. • With regard to electromagnetic radiation and its implications for safety, standards also differ between countries and environments. As for our country, below 0.3 µT is harmless to human body, from 0.3 µT to 0.4 µT is called a warning value, and above 0.4 µT is considered strong radiation.
In a computer, motherboard processor power supply has an average value of 0.174 µT, and graphics card power supply averages 28.4 µT, so level of radiation is simply amazing. So a good chassis is still very important.
