WebFeb 16, 2024 · Average U.S. Doses and Sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground, and man-made sources such as medical x-rays. According to the … WebThe total radiant flux (power output) of the Sun is about [math]3.8\times10^ {26} [/math] joules per second. Earth’s energy usage in 2013 was about [math]3.9\times10^ {20} [/math] joules. So the Sun’s energy output in a second is almost exactly 1,000,000 times greater than all of Earth’s energy consumption in the year 2013.
