The simple answer I found is "maybe". Asbestos was banned for use in popcorn ceilings in 1977, so there was probably a lot of it still floating around in 1979. read the information on the epa website, and then decide for yourself what to do

I would use extreme caution if you tried to remove it. wear gloves, long sleeve shirts, a respiratior, not just a cheap dust mask, and then clean the house from top to bottom when you are done.
