How far is it from laptop to avoid or reduce radiation?

We know that computer monitors will produce ionizing radiation (low-energy X-rays), non-ionizing radiation (low-frequency radiation \ high-frequency radiation and optical radiation) and acoustic radiation, and very few will leak. According to the measurement, the annual additional dose of ionizing radiation (low-energy X-rays) to workers working 70cm away from the monitoring station is far below the public dose limit set by China. Moreover, liquid crystal displays do not generate electromagnetic radiation and acoustic radiation. Therefore, pregnant women can use computers with confidence. However, it is worth emphasizing that in order to avoid the adverse environment in the organogenesis stage affecting the fetus, it is recommended to reduce contact with computers in the first three months of pregnancy and not watch TV for a long time. Otherwise, the radiation and electromagnetic waves emitted by computer screens and TV screens will have adverse effects on the fetus. In addition, computers and televisions generate high-voltage static electricity at work, which makes indoor cations saturated and negative ions in the air insufficient, which interferes with the mood and metabolism of pregnant women and affects the development of fetal brain.
