There are two main types of water hammer suppressors, those equipped with pistons and those that are not equipped with pistons. Among the various means for damping the pressure peak of water hammer, varieties equipped with a piston are the most effective. Homes over 25 years old are the most likely candidates for water hammer, as the only method used to control water pressure when these homes were built was to install vertical pipe risers along horizontal pipe runs at 24 intervals. Over a long period of time, these risers can fill with water, creating an ideal breeding ground for bacteria that can end up contaminating your home's drinking water.
Ionizing radiation has a flow of several microparticles or electromagnetic fields, which have the ability to ionize a substance. In everyday life, ionizing radiation denotes penetrating radiation, a flow of gamma rays and particles (alpha, beta, neutrons).
Ionizing and Non-Ionizing Radiation Ionizing radiation has so much energy that it can remove electrons from atoms, a process known as ionization. Ionizing radiation can affect atoms in living things, posing a health risk by damaging the tissue and DNA of genes.
Under certain conditions of use, ion generators and other air purifiers that generate ozone can produce levels of this lung irritant significantly above levels considered harmful to human health. A small percentage of air purifiers claiming a health benefit may be regulated by the FDA as a medical device.
