Conversion from flux to R and Gy

Energy (keV): (must be between 1 and 20000)

flux is A x 10B photons/sec/mm2

[Answer section]
Exposure rate is Roentgen/sec
Dose rate is Gy/sec or rad/sec

A comment by Dr Jun'ichiro Tada is here (in Japanese).

Roughly, rad/sec is close to Roentgen/sec, that is, Gy/sec is about 1/100 of Roentgen/sec.
