...addition to a careful study of the relative atomic arsenals of the signatories and the possible diplomatic effects of the treaty, the Senate would be wise to consider another set of statistics, released Saturday by the Public Health Service. According to the Service's measurements, the amount of strontium 90 in the average litre of milk in this country was twice as great last May as in May 1962. Federal Radiation Council scientists estimate that the level of radiation was even higher for June and July. This sharp increase in radioactivity in the atmosphere is a direct result...
...Working on techniques for removing strontium 90 from milk...
...submicroscopic pores that permit the passage of small atoms with positive electric charges. Milk is made to flow along one side of a membrane; on the other side is a solution of such salts as calcium and sodium chlorides that are naturally present in milk. If the milk contains strontium 90 atoms, they pick up positive electric charges from a current flowing through the solution. Then they slip through the membrane and lose themselves in the harmless salts. Dr. Gregor thinks that his process can extract 90% of the strontium 90 from milk at the cost of about...
...Strontium 90, however, is not the only kind of radioactive fallout that can get into milk; iodine 131 can become a problem too. But its threat does not justify the scare advertisement (showing a bottle of milk with a death's-head label) that the National Committee for a SANE Nuclear Policy ran last week in the New York Times...
...While strontium 90 is long-lasting (half life: 28 years), the half life of iodine 131 is only eight days. If the iodine 131 level in milk ever rises above the danger point, the prescription will be simple: stop drinking fresh milk for a couple of weeks. No one need go hungry. Most other foods will be free of iodine 131; they will have been stored long enough to let its activity fall to the vanishing point...
