Introduction

The present issue of the Newsletter continues the theme of exploring societal and/or scientific implications of hormesis ASSUMING it exists and displays a stimulatory range of up to 10-fold, and a maximum stimulatory response of approximately 40-60% above the control within approximately 4-5-fold of the No Observed Adverse Effect Level (NOAEL) (Calabrese and Baldwin, 1997, 1997a) as represented in Figure 1.

Various experts were invited to assess whether such a phenomenon, if it were to exist, would be important for society to carefully consider. Thus, even though a person agreed to contribute should not be assumed that they would necessarily be supportive of the hormesis hypothesis per se.
