Potential sources of radiation

	Food (especially berries and mushrooms) Food (especially berries and mushrooms) will definitely accumulate radiation if grow in contaminated areas. These are not the best ingredients for your nutrition or home-made jam. Mushrooms tend to absorb radiation from soil as well. It is important to know that radiation which gets inside of our bodies is the most dangerous. Check radiation safety of your food (especially mushrooms and berries) and enjoy safe cooking.
Home and office It is great to have excellent workplace in a comfortable office or have some rest sitting in your favorite chair at home. But is there any chance you can be exposed to radiation? Unfortunately, yes. Furniture can be made of radioactive wood as it absorbs radiation. Granite can have high radiation level as well. Check the radiation level of all your furniture.
	Construction Remember that construction materials can contain natural radionuclides. That is why when building, choose the materials carefully as they can pose a great threat to your health. When moving to a new place, be sure to check that no radiation is there.
Playground Radiologically contaminated toys can harm your child’s health. Even a sandbox on a playground can pose a danger. Control radiation level around to be sure you chose a right place to play with your kids.
	Cash Cash can be radiologically contaminated for definite purposes. The most common one is to track money during special operations, but sometimes these banknotes can end up in our wallets. Even a small amount of radiologically contaminated banknotes can harm a large number of people. Be safe when deal with cash.
Garden Radioactive fallouts may contaminate soils in any corner of the world. Be sure to check radiation level in your garden if you don’t want to raise contaminated fruits and vegetables. Radiation which gets inside of our bodies is the most dangerous.
	Travelling When travelling you can come across the places of buried radioactive scrap metals or others contaminated objects. Caving is such a fun if you are not exposed to high radiation level there. It is better to enjoy outside activities if they’re safe.
Jewelry We should pay great attention when buying necklaces, rings or other jewelry. Precious metals and stones can have high radiation level, especially zirconium which is the most commonly used in jewelry items. That is why you should be careful if you don’t want to pay “high” price. Jewelry should be decorative, not destructive.
