A comparison of the MPE predicted by ANSI Z136.1 for skin to our experimental results on blood vessel tissue. Note that the ANSI Z136.1 standard defines the MPE as $10\times$ smaller than the dosage that will cause damage 50% of the time (EC50). Thus the MPE must be multiplied by 10 before comparing it to the applied dosage.
