My iPad 2 is about 2.5 years old. About a year ago the screen cracked from a fall and i replaced the screen from some shop and there was however still a noticeable misalignment or cracks showing on the corners. I then re cracked the screen months later and it has bits of glass shattered at the top right corner. I've been using it ever since but do you think these two occurrences are likely to have increased the amount of radiation the iPad emits? I hope i gave a good description. Could the broken glass and the corners that show the inside of the iPad cause more radiation especially harmful radiation and the fact that it dropped twice and even on the replacement screen.
