Sarah, I'm assuming you're worried radioactive fallout from Japan (as a result of the earthquake and tsunami) might reach Europe. The computer models so far say a negligible amount of radiation (not sufficient to affect human health) may reach Canada and the USA. Prevailing winds mean that radioactivity would need to travel across the US and the Atlantic before reaching Europe. As it is spread by the wind it reduces in severity even further. I don't think you have anything to worry about there.
Libya and the unrest in North Africa: if you're staying in Europe it should have no impact on you (it is a pro-democracy movement and Europe is democratic already).
To be honest, the most significant risk to your safety in Europe is injury in a traffic accident, or getting drunk and falling down.
Nowhere is totally "safe" (just think of the knives in your kitchen), but if you take reasonable precautions and use common sense you'll be fine.
Read up on some of the travel tips and safety hints we have at WorldNomads, maybe starting with this one http://journals.worldnomads.com/safetyhub/story/22027/Worldwide/Welcome
then go and have a great time. Don't forget to start a WorldNomads journal so we know how much fun you're having!
