If passed and signed, his bill would create a law that would allow the tracking of low-grade radioactive materials such as plutonium and uranium, materials routinely used in hospitals, laboratories and power plants.

In addition to their beneficial properties, the radioactive materials can also be used to create so-called "dirty bombs."

As to the mechanics, pilfered nuclear materials are wrapped around the core of conventional explosives. When detonated, the materials create a limited area of nuclear contamination.

With the number of terrorist groups operating globally today, it is clear that a law tracking nuclear material be enacted, no matter how limited the threat of serious contamination or death from radioactive poisoning.

It is easy to see how the successful detonation of such a bomb could blast a real hole in America's morale, not to mention the panic and subsequent loss of life any nuclear event would be bound to trigger.

The head of the Nuclear Regulation Commission says there is no way under current law to keep domestic security aware of missing material, since industry is not required to report it.

For a cost estimated to be no more than $1 billion, the government would finally be able to get a handle on the traffic in low-grade radioactive materials.

This certainly wouldn't have any effect on current fears that atomic bombs could be exploded in America, but that is a concern that must be addressed internationally.

Meanwhile, Schumer's proposal to clamp down on the traffic in legitimate materials makes eminent sense and should be supported by anybody concerned with domestic security.

And isn't that all of us?
