I live in a area where Lead based paint is an assumption, and radon is a massive issue. The cost of getting work done is tremendous so I'd rather do it myself.

I live in a area where Lead based paint is an assumption, and radon is a massive issue. The cost of getting work done is tremendous so I'd rather do it myself. How can this help me know what work I can DIY and what work is safer to hire out to someone who is an expert. Sure I can pay someone 2x as much to work on my kitchen but what is the relative risk to my health due to lead paint. It'd be nice if I could start a project and have sampling on a daily basis similar to what rad techs or a metric of information on how much lead is in the air as I'm working.
