Why is radon gas dangerous at high levels a. it emits gamma rays that cause burns b. it emits beta particles that cause burns c. it emits alpha particles which damages tissues

Radon produces a radioactive dust in the air we breathe. The dust is trapped in our airways and emits radiation that damages the inside of our lungs. This damage, like the damage caused by smoking, increases our risk of lung cancer.

hope this helps 

btw i would say c unless theirs a d

C. It emits alpha particles which damages tissues.Explanation:

The radon is the decay byproduct of radium which emits alpha rays to convert into the lead or polonium. The alpha particles have less penetration inside the cell than the beta particle or gamma rays and have the more dangerous effect than these other days. In the environment, the high presence of radon enters into the lungs through breathing and start to decay. In their decay, it emits alpha rays, which acts as the carcinogenic agent in the body.

So, the right option is (C) as it emits alpha particles which damage.
