Yes it is possible to protect yourself and especially your kids, because they haven't asked for this! What is most important for the human body is not to be hit by any radiation at night, because it will reduce production of the hormone melatonin and in the long run shot it totally down. Melatonin is made by the pineal gland and help controlling your sleep and awake cycles. It is an antooxidant and it has an effect on most biological and physiological processes. Which means if your melatonin production is low or gone, you risk of getting future disease including cancer is much higher. One could say it has an important role in the autonomic processes happening in the immune system of the body. If interested check out some of my recent posting regarding this topic.
