Notice: - Although the method that determine radiation
dosage by skin type is simple, but not as accurate
as MPD or MED.
- Specific drugs may increase the skin sensitivity to
light, thereby to affect the determination of skin
type.
- It is also important to learn about the patient’s
reaction after long-term sun exposure to
determine radiation dose. If two patients are the
same skin type, the slow tanned one should
adopts a lower dose.
