求翻译：降低传输率，容易发生掉包或断线，安全性较低，有一定距离极限性，一般小于10米，超过则无法搜索到，而且信号随距离增大和阻碍物增多而衰减，有一定辐射性是什么意思？

Reduce the transmission rate, prone to substitution or disconnected, less secure, there is a certain limit of distance, generally less than 10 meters, more than you can not search, and the signal increases with distance and obstructions increase and decay, there is a certain radiation

Reduces the transmissibility, easy to occur makes a fraudulent switch or the broken line, the security is low, has certain distance extreme, is smaller than generally 10 meters, surpasses is unable to search, moreover the signal increases along with the distance with the encumbrance increases weaken

Reduced transmission rates, prone to switch or break, less length limit, generally is 10 metres over you cannot search and signal attenuation as the increasing distance and obstructions, a certain radiation

Reduce the rate of transmission, prone to switch or break, less secure, some distance from the limit, generally less than 10 meters, over to you will not be able to search, and signal attenuation with distance increases, and increased obstacles, and, have some radiation
