WebIn radiation therapy a skin dose of 6 to 8 Gy with 200 kV is required for erythema to occur. Radiation of higher energies requires larger doses to produce the same degree of erythema, since in these cases the maximum dose is received in deeper tissues below the skin. http://amos3.aapm.org/abstracts/pdf/166-57926-15651646-171119-1793273006.pdf
