Two of the three workers inside the plant received more than the lethal dose of seven sieverts (a sievert is the unit that measures the intensity of radiation's impact on the body).

However, satellites are shielded from that radiation, and the intensity of the radiation in the inner belt is relatively stable.

"Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere, " explained Prof Bill Webber from New Mexico State University in Las Cruces.

Once the cancerous area is precisely targeted, only the intensity of the laser radiation needs to be turned up in order to irradiate, or burn off, the tumor.

Given the risks of aiming such a powerful beam of high-intensity radiation at an Earth ground station, as well as the cost of building billions of dollars in infrastructure to collect the energy in space, the efficiencies you can get from terrestrial solar power seem a safer bet--at least for now.

Based on their models, the authors suggest that the high radiation intensity of the inner belt could persist for as long as a decade.
