Parents removed popcorn ceiling without having it analyzed. What's done is done, but I'm extremely concerned about asbestos exposure.

Our home was built in 1974, and it's unclear if the popcorn ceiling dates back to that time or if it is more recent. I know that up until the 1980's, asbestos was a major component in a lot of building materials, including popcorn textured or acoustic ceiling.

The other day, I came home to find that my dad had removed the popcorn ceiling from the main living room, by thoroughly wetting it and scraping it off with a flat scraping tool. Despite wetting the material, I know that IF asbestos was present in the ceiling, we have likely been exposed. What's done is done. If there was asbestos in that ceiling, then we had at least some level of exposure to it once he removed it. To be clear, I knew my dad was planning on removing the ceiling, but had figured he'd hire someone else to do it. Wrong. And although one can theoretically remove asbestos materials themselves if they have proper protective gear on, my dad...did not. He wore a basic paint mask, which is insufficient for the task.

Also, I'd like to reiterate that I'm not even sure if the ceiling contained asbestos at all...and he doesn't plan on getting it analyzed, still. My question pertains to the risk we are at now that we've been, theoretically, exposed. How likely is it that this exposure will have serious adverse health affects later in life? I realize that no level of exposure is safe, but are we better off than those who are frequently exposed via job sites, or is the risk all the same, regardless? If anyone (especially people with experience in this area) could help me out, I'd really appreciate it, because regardless of the fact that I can't change what's happened, I'm experiencing severe anxiety over this situation.

Tldr; a hypochondriac worried about possible health affects of asbestos exposure after a single-room ceiling renovation project.
