From a speech by Dr. Bailus Walker Jr., commissioner of public health for the Commonwealth of Massachusetts on March 19 to the Harvard School of Public Health:

The bottom line is that these 40 years of unrestrained nuclear weapons development have triggered an unprecedented arms race, failed to bring real security and brought the world to the brink of a public health disaster -- annihilation.

It has weakened our competitive position in international trade, and it has resulted in a rapidly growing national debt and deteriorating land and resource base which exacerbates health and social problems.

What we must have is a meaningful near-term arms control objective that would have a beneficial impact on nonproliferation as well as international relations, specifically U.S.-Soviet relations.

A comprehensive test ban is such a measure that will check the unraveling of the nonproliferation regime.

A comprehensive test ban has an important role in arms control.

It was once, and it must be again, the centerpiece of such an effort.

It is still a symbol of hope here at home and throughout much of the world which values human life. . . .

Because the benefits of a comprehensive test ban outweigh the risks and because it is a significant step towntrol and all of its inherent benefits to public health, we are today calling on all health workers in Massachusetts and around the world to immediately learn more about comprehensive test ban and to develop an aggressive campaign to explain to colleagues, patients and friends why we must stop all nuclear explosions.
