For the theory and LQ model, please, visit the introductory
page. Often *α* / *β* = 10 Gy is used for tumor and *α*
/ *β* = 3 Gy is used for normal tissues if better estimates are
not available. EQD2 is the equivalent dose in 2 Gy fractions and BED is
the biologically equivalent dose.

## New number of fractions based on new dose per fraction:

If you need to calculated new dose per fraction based on the known number of fractions fraction use the other calculator.
