Radiation therapist and artist Gerry Ash has been painting radiation masks for over 30 years, mostly for children in a Canadian hospital, but sometimes for adults too. "I would never refuse to paint for someone," she tells PS. Her masks can take up to 20 hours to paint, plus 2-3 hours of prep work depending on the complexity. This Wonder Woman-themed mask was created for a breast cancer patient with brain metastases (when cancer cells travel away from their original location). Over the years, Ash estimates she's done hundreds of masks, decorated with everything from unicorns to Shrek ears.
