Why is alpha radiation dangerous?
Understand the Problem
The question is asking about the dangers of alpha radiation, specifically what makes it harmful to living organisms. It will likely involve discussing how alpha particles interact with matter and the potential effects on human health.
Answer
Alpha radiation is dangerous mainly if inhaled, ingested, or enters wounds, damaging internal tissues.
The final answer is Alpha radiation is dangerous primarily when alpha-emitting materials are inhaled, ingested, or enter the body through a cut, where they can cause significant damage to internal tissues due to their high energy and inability to penetrate skin from outside.

More Information
Alpha particles are charged and have high linear energy transfer (LET), meaning they release their energy over a short distance, causing intense localized damage inside the body.
Tips
One common mistake is overestimating the penetrative ability of alpha particles; they are easily blocked by skin or paper but pose serious risks when internal.
