There are four commonly recognized levels of radioactivity: background, elevated, high, and extremely high. Background refers to the natural level of radiation present in the environment. Elevated refers to slightly higher levels of radiation, typically found in certain regions or situations. High levels of radioactivity pose a significant risk to human health and safety, requiring prompt action to mitigate exposure. Extremely high levels are extremely dangerous and can cause severe health effects immediately.

Is baldness also an effect of radioactivity?

It's not technically baldness, I suppose "hair loss" is more accurate. But, yes, radioactivity is physically harmful and loss of hair is a common result from heavy exposure. We're talking nuclear reactor or chemo-therapy with radioactive materials levels, not "stand in front of the microwave" or "get sunburnt" levels...
