SOME EFFECTS OF EXPLODING PHOTOFLASH BOMBS ON THE TRANSMISSION OF RADIO WAVES,
Abstract
The explosion of a specific photoflash powder is considered as a simple chemical reaction. The composition of the powder is 30% Ba(NO3)2, 30% KClO4, 40% Al. The temperature of the reaction is calculated to be 4000K and the pressure developed is 6000 atmospheres. The initial Saha equilibrium electron density developed is 10 to the 20th power electrons/cc. These electrons, uniformly distributed in a spherical cloud of aluminum vapor and nitrogen (gaseous explosion products), would make such a sphere (up to 10 ft radius) opaque to radio waves of frequencies up to 10,000 megacycles/sec. For such frequencies, the ratio of flux incident upon the cloud of radius a to that scattered a distance R away is roughly S sub I/S sub S = 1/4 (a/R) to the 2nd power. For large radii, the attenuation and reflection coefficients can be determined. (Author)
