ICC Publishes Shipping Regulations The ICC has announced the new regu lations adopted for transporting radioac tive materials which will become manda tory on Jan. 21, 194S. Their adoption is optional prior to that date. These materials are included in a newgroup of dangerous articles called Class D poisons. T h e y are denned as follows: Radioactive material is any material or combination of materials that spontane ously emits ionizing radiation. For the purpose of these regulations radioactive materials are divided into three groups ac cording to the type of rays emitted at any time during transportation, as follows: G R O U P I—Radioactive materials that emit gamma rays only or both gamma and elec trically charged corpuscular rays. GROUP II—Radioactive materials that emit neu trons and either or both types of radiation characteristic of Group I materials. G R O U P III—Radioactive materials that emit electrically charged corpuscular rays only, i.e., alpha or beta, etc. Λ new section (367) of the regulations lists the exemptions which are permitted. Section 36S, also new, covers the packing requirements in detail. Specific labeling and marking requirements are enumerated in Section 369. Two new diamond shaped labels are required, one for Group I and 11 and the other for Group III. In addition, a new car placard for radioactive material? is prescribed. Spec. 2 R metal tubes (inside contain ers) arc required for packing some of these materials.
