  • aeg, mis kulub, et teatud radioaktiivse aine aktiivsus väheneks radioaktiivse lagunemise tõttu poole võrra
  • the time required for the activity of a given radioactive species to decrease to half of its initial value due to radioactive decay
Good to know
  • Poolestusaeg on iga radioaktiivse aine iseloomulik tunnus, mis ei sõltu selle hulgast ega seisundist. Teatud isotoobi efektiivne poolestusaeg on aeg, mis kulub, et selle hulk organismis väheneks poole võrra nii radioaktiivse lagunemise kui ka bioloogilise eritamise tagajärjel.
Good to know
  • The half-life is a characteristic property of each radioactive species and is independent of its amount or condition. The effective half-life of a given isotope is the time in which the quantity in the body will decrease to half as a result of both radioactive decay and biological elimination.
