Everyday Use

Bottled water is one,if not, the most common way for humans to consume water for everyday use. Drinking water from water fountains in a public building will also contain very low levels of radioactivity.

We drink more water when exercising, talking, and when we are thirsty. The amount of water that each person needs to drink is about a half gallon a day. We are exposed to this small amount of radiation when taking a shower, bath, swimming in a lake or pond, because of the small amounts of radiation in the soil that the water absorbs.

Radionuclides

According to United States EPA , "Most drinking water sources have very low levels of radioactive contaminants, called radionuclides, most of which ae naturally occuring. Most radioactive contanimants are at levels that are low enough to not be considered a public health concern."

"The Environmental Protection Agency (EPA) regulates radionuclides in drinking water to protect public health. Radionuclides in water at amounts greater than drinking water standards may cause heatlh problems."

"Processing practices addressed in the cGMP regulations include protection of the water source from contamination, sanitation at the bottling facility, quality control to ensure the bacteriological and chemical safety of the water, and sampling and testing of source water and the final product for microbiological, chemical, and radiological contaminants."

Types of Radiation in Water

  • Radium
  • Uranium
  • Radon

Treatments for Types of Radiation in Water

  • If your water is tested and its total is more than 226 pCi/L, then the best treatment for your water is to use a water softener. The softener changes the radium to sodium or potassium.
  • Another treatment plan that you can take is reverse osmosis. This undergoes a process of pressurized water that goes through a membrane which the radium cannot pass through.
  • If your water is contaminated with a higher amount of uranium then you may perform an anion exchange. This treatment has a similar outcome as the water softener, but it turns the uranium into chloride.
  • Lime softening is best used for homeowners with a high amount of uranium in their water.
  • To help reduce the amount of radon in your water, you test the air, if it is above the recommened amout, then aeration will help remove the unwanted radon.
