Exposure to radiation can come from various sources including: X-rays, radiation treatments, sun-tanning parlors (banned in Australia), warfare agents, and sunlight. Some estimate humans need about 15 minutes of exposure per day to the arms to obtain needed benefits, preferably early morning and late afternoon. Excess exposure to the sun’s ultraviolet (UV) rays can lead to skin cancer due to gene mutations (melatonin, for example).
Prevention Strategies? Human being need sunlight so obtain moderate exposure, preferrably not in the hot mid-day sun. Use proactive protection and obtain regular skin checks as needed. Negotiate with your healthcare professionals to obtain x-rays (etc) based on identified need.
