A large group of people perceive risks of RF exposure as likely and even possible severe. It is explained that RF radiation cannot be directly carcinogenic. RF heating is well controlled by (inter)national power restrictions and exposure limit recommendations. Long-term effects are not fully known and research concerning possible effects is ongoing. Awaiting these results, we propose to use the ALATA principle concerning transmit powers. For wireless energy transport we furthermore propose to place RF base station and wireless sensor nodes on the ceiling and direct the radiation over the ceiling. The benefit is two-fold: humans are not subject to electromagnetic radiation and energy transport is not blocked by humans.
