How to get my dad to smoke outside?

He smokes all the time and I really hate having to be exposed to 2nd hand smoke all the time. It makes me angry that he knows all the risks but still puts me in danger. I am angry that I am forced to be near it. It is really effecting me. I have had lung problems my whole life and now I have chronic bronchitis. I know it's his house too but I just can't risk my safety. I love him but he won't quit and that's his choice. But I am only 16 and fear more side effects. What do I do? No rude answers please. Thanks.
