Testing for Radon. Perform a radon test before you close on the property. Use EPA testing guidelines to choose a test and tester. Ask the tester how you can prevent device interference during the test. If radon levels are above 4 pCi/L, or your own stated maximum, use mitigation techniques for reduction, then test again.

They did research and came up with this spectacular invention of the worldâs most sensitive scale. The device can significantly measure the smallest unit of a mass, or also known as the yoctogram which is just one septillionth of a gram.
There are a couple of different ways to measure how âbigâ something is. The first is an objectâs mass (how much matter it contains) and the second is its volume (how much space it takes up). The smallest and largest planets in our solar system are Mercury and Jupiter, respectively. The smallest planet in regards to both mass and volume is Mercuryâthis tiny world is nearly 20 times less massive than Earth, and its diameter is about times 2 Â½ smaller.
