Do you use your mobile when you know it's battery has gone down to 20%?

I know it's not good, but I still use my phone even when the battery of it goes down to 20%. I have read it is not good because it emits bad radiation when there is low battery. Do you think it emits harmful radiation? Do you use a mobile phone even when it has a low battery?

I always try my best to charge my phone before it gets to 20% the few times I we actually allow my phone get that low is either because I want a fresh charge from 0% or there is no where to charge my phone.
