This is a summary of recent congressional actions not reported elsewhere in The Post. SENATE

Drug Sales

The Senate approved, 91 to 7, a measure allowing the export of drugs that have not been approved for sale in the United States. Under the bill, drugs not approved by the Food and Drug Administration for use in the United States could be exported under certain conditions to specified developed countries with drug-approval systems capable of dealing with potential safety problems, and countries with health problems that do not exist in the United States. (S1848/ May 14) HOUSE

Drinking Water

The House approved, 382 to 21, a conference report to a measure toughening the nation's major law protecting drinking water. The agreement reauthorizes the Safe Drinking Water Act, establishes a new underground drinking water protection program, directs the Environmental Protection Agency to begin setting standards for specified contaminants, and bars the use of lead in drinking water systems. (S124/ May 13)

Atomic Test Victims

The House approved, by voice vote, a measure allowing individuals exposed to U.S. atomic weapons tests to sue the U.S. government for injuries from radiation exposure. The legislation makes the United States the sole defendant in atomic radiation cases. From 1946 to 1962, contractors conducted 235 atomic tests for the government, involving about 250,000 active-duty military personnel and 150,000 civilians. Many of those involved in the tests have claimed various long-term medical injuries, including leukemia and bone marrow cancer. (HR1338/ May 13)

Prison Rape

The House approved, by voice vote, a bill that would make homosexual rape in federal prisons a crime. The bill would make it a federal crime to rape a man or woman on federal property, and it expands federal jurisdiction to include all federal correctional, detention and penal facilities. The measure also would repeal immunity from prosecution for rape of a spouse. Sexual offenses are defined in gender-neutral terms, and sexual abuse that does not involve intercourse is treated as a crime. (HR4745/ May 12)

Alien Workers

The House approved legislation allowing aliens on U.S. fishing vessels to go ashore when in Guam. The change follows complaints that restrictions on alien crews discouraged vessels from stopping there. Currently, alien crew may not take shore leave in the United States, including Guam.
