Available in PDF, EPUB and Kindle. Book excerpt: The penetration into concrete of gamma radiation from fallout has been measured in an idealized geometry as a function of time after the detonation of a nuclear device. At the same time, the exposure dose rate in air at heights of 3 and 9 ft above the ground was measured with two detectors suspended from a tower and shielded from above with lead so as to be sensitive primarily to radiation from fallout on the ground. For this test a 'sandwich' made of seven concrete slabs, forming a mass of concrete with face dimensions large enough to reduce edge effects to a negligible amount, was buried with its top surface flush with the ground. Remote-reading detectors were placed between the concrete slabs, thus permitting measurements of dose rate as a function of depth in concrete. The concrete mass and the tower were located in the center of a cleared and leveled area approximately 200 yd in diameter. Thus the gamma radiation at the detectors originated from an essentially infinite-plane source of radiation. Results are presented both as a function of time after detonation and of depth of penetration of the radiation into concrete. A comparison of the results with theoretical calculations is made.

Download or read book Ground Penetration of Gamma Radiation Into a Hole in a Simulated Cs137 Fallout Field written by C. E. Clifford and published by . This book was released on 1959 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dose distributions in a cylindrical foxhole due to ground penetration of 0.66 Mev gamma radiation from Cs137 sources near the lip of the hole have been measured for a "ground" of concrete. Ninety percent of the dose due to ground penetration came from contamination within 1 foot of the edge of the hole. Measurements were also made of the dose distributions produced by the lip penetration of a lucite "ground". It was found that the dose produced by a single source under conditions of lip geometry could be calculated with reasonable accuracy by using one half of the infinite medium buildup factor for lip penetration distances of less than 8 mean free paths.

This book was released on 1964 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report is a discussion of the technical assumptions underlying the methods currently recommended by the Office of Civil Defense (OCD) for calculating protection afforded by structures against fallout radiation.It discusses methods for calculating the contributions from radioactive sources on the roof and on the ground surrounding a simple one-storied building.It shows in detail how each technical chart in the OCD Professional Manual is derived from basic data on radiation penetration developed by Dr. L. V. Spencer.Charts from the Professional Manual and relevant curves from Spencer's work are included.(Author).

Available in PDF, EPUB and Kindle. Book excerpt: Graphs of the change in input impedance of electrically short dipole antennas in the presence of an isotropic and homogeneous ground are presented, considering four types of antennas: horizontal and vertical, electric and magnetic dipoles.Curves of the change in both the input resistance and reactance are shown for a wide range of values of the frequency, antenna height above the ground, and electromagnetic ground constants.(Author).
