RadTats were designed with both patients and providers in mind. A simple application process with no maintenance. Providers no longer worry about loss of marks from lack of care, accidental sticks, or other adverse issues from conventional markers. Patients no longer worry about losing marks while bathing or exercising, unwanted emotional reminders or allergic skin reactions from adhesive coverings. RadTat is skin marking for radiation oncology. This product will last up to two weeks with little to no maintenance by patient or care provider. This is not a sticker. RadTat provides a quick, simple solution that lasts.
