Alpha emitters

GENERAL INFORMATION
Most drinking water sources have very low levels of radioactive contaminants ("radionuclides"), most of which are naturally occurring, although contamination of drinking water sources from human-made nuclear materials can also occur. Most radioactive contaminants are at levels that are low enough to not be considered a public health concern.

Alpha emitters are atoms that, in order to become more stable, emit an alpha particle (a helium nucleus). These alpha particles are relatively large and can be emitted by a variety of atomic transitions and can cause damage to molecules in the body including.

HEALTH EFFECTS
Some people who drink water containing alpha emitters in excess of the MCL over many years may have an increased risk of getting cancer.

Standard value 1: 
15.00
Standard units 1: 
pCi/L
Input units: 
pCi/L
Contaminant group: 
Radionuclide
Standard type 1: 
MCL
Action is recommended 1: 

MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Alpha emitters levels were detected in your water sample to exceed the maximum contaminant level (MCL).

Action is optional 1: 

ACTION IS OPTIONAL
Alpha emitters levels were detected in your water sample but do not exceed the maximum contaminant level.

Major sources in drinking water: 
Decay of unstable nuclei in natural and man made materials.
Treatment options: 

TREATMENT OPTIONS
Reverse Osmosis (RO): RO system to remove radionuclides depends on a number of factors, including pH, turbidity, iron/manganese content of the raw water, and RO membrane type.
