  Radioactivity is something we live with constantly – it’s always there in relatively small amounts. Around the world, naturally occurring, higher-than-average levels of radioactivity are found in various types of beaches and soils, among other places. Meanwhile, most concrete is radioactive, though levels obviously vary. In the US, it is possible to get your home tested for radon gas – which is produced slowly over time by radioactive construction materials. Even the human body is slightly radioactive because we contain elements like potassium-40, which decay.

Vitamin D – natural Source

During the bleak winter months of short days and cloudy skies, many people may seek out the benefits of sunshine in bottle form and reach for supplements of vitamin D. Made naturally by the skin when exposed to sunlight, this vitamin is needed to maintain healthy bones, teeth and muscles and to prevent them from becoming brittle and at risk of fracture.

In spring and summer in the far regions of the Northern and Southern Hemispheres, such as the northern US and New Zealand, people tend to produce enough vitamin D through sunlight on their skin and foods in their diet. The vitamin helps the body absorb calcium to promote bone growth.

But during autumn and winter, levels drop. It helps to eat the right foods, such as oily fish, egg yolks, red meat and liver, to keep levels high inside the body -- which not everyone can achieve adequately. Fortified foods, including milk, cereals and spreads, provide the most vitamin D in the American diet, according to the National Institutes of Health.
