A plot of radioiodines produced by thermal fission of U/sup 235/ as a function of time after fission is presented, and a high-expansion fire control system for glove boxes using argon-- aqueous ammonium lauryl sulfate foams is described. In development of analytical and measuring methods, an infrared spectrophotometric analysis of vapors in calibration bottles is reported along with modification of the Davis halide meter for continuous atmospheric monitoring of methyl chloroform and development of arc sensitivity conversion factors for use with a 3.4-meter spectrograph in the case of 33 elements. In other work a long-service sprayable polyurethane flooring material was developed which provides safety in high-explosive handling areas. Shielding for the proposed increased Cockcroft-Walton ion accelerator beam power level is discussed. Results of floor finish evaluations are given in which three were selected as superior in regard to antislip qaalities, lasting appearance, and cost. The description of a method to convert from fail-safe fire detection circuit to a fully supervised circuit is included along with nomographs for simplification of air-sampling calculations. (J.R.D.)
