Effective Half-Life Calculator

Calculates the effective half-life considering the metabolism of radioactive material taken into the body.

Radioactive material that is ingested is eliminated from the body by metabolism.
The time when the quantity becomes half by metabolism is biological half-life.
Effective Half-Life
    1. Radioactive element
    1.    [ Physical half-life
    1.    [ Biological half-life

Radioactive iodine tends to be accumulated by the thyroid gland.
When strontium 90 and calcium 45 are taken in into bones, the biological half-lifes are as long as 50 years.
