An electrostatic precipitator and a newly developed filter paper are compared for efficiency, reliability, availability, and ease of use. The aerosols collected in either case are counted for alpha activity in a cylindrical pulse chamber, the design of which is an adaptation of the breech-locking air alpha chamber. Vapor and gases are not collected by either instrument, unless occluded on particulate matter. |

One-day-old rats were subjected to one -half (anterior or posterior) body irradiation by the beta rays of p(32). The skin exposure on the body was about 1,700 to 2,000 rep. The skin exposure on the tail, hands, feet, forearm, and leg was somewhat less than twice this. The animals were sacrificed at 200 days of age. No cutaneous tumors occurred. The irradiated animals weighed 5 to 10 per cent less than the controls. Males and females reacted alike. Changes were observed only in the part directly irradiated. The 'anterior' animals had significantly smaller ears, skulls, and forelimbs; the 'posterior' animals, tails, hindlimbs, and testes. Skeletal measurements are given. No effect was observed on the stomach, kidneys, liver, or heart. |

In the early phases of nuclear research, scintillation counters proved valuable for detection of alpha particles. In this technique, as perfected by Rutherford and his co-workers, scintillations produced by the excitation of fluorescent and phosphorescent screens were observed visually. The method has been revived in modern form, principally by Kallman, with the use of photomultiplier tubes for the observation of light pulses, and large, transparent crystals for the conversion of as much of the energy of a penetrating particle into light as possible. A wide range of fluorescent materials has been tested by various workers. On the basis of reported efficiency and response time, the work at this laboratory was initiated using naphthalene. The first experimental arrangement consisted of a 1P21 P.M. tube mounted in a glass container stuffed with moth flakes and immersed in liquid air as shown in. With radium gamma ray source, a ratio of about 20 was observed between the counting rate of this set-up as compared with that of the photomultiplier surface alone exposed to the gamma radiation under otherwise identical conditions. As a consequence of the sensitivity (about 10 per cent gamma counting efficiency) of even this crude and inelegant device, as well as of its very simplicity, a program was undertaken with the aim of devising a rugged and adaptable basic counter unit. This program received added impetus when it was discovered that the much greater usable light output of anthracene made possible the elimination of the refrigerant. With respect to pulse width, it will be seen that the fortuitous condition exists whereby the minimum, independently observed pulse width coincides with the maximum resolution of simple, fairly conventional electronic recording equipment. |

The beam of 200 Mev deuterons in the 184-inch cyclotron gives rise to a conical spray of fast neutrons. (Refer to papers A 10 and A 11 of this meeting) with an upper limit of neutron energy somewhat above 100 Mev. The angle of the cone from axis to half-height is about 5.5 for a target of high atomic number, as measured by Helmholz, MacMillan, and Sewell with carbon detectors. In planning for final shielding of the cyclotron It was necessary to study the attenuation of the neutron beam in concrete. Due to the nature of the information desired the experimental arrangement employed was that shown in Figure 1. The monitor and detector employed were aluminum-walled ionization chambers, with DC Amplification, indicating on microammeters placed outside the magnetic field of the cyclotron. With this same arrangement data were also obtained with water as an absorber, contained in steel tanks made to fit Into the cavity and in front of it. Results of these measurements are given in Figure 2(a). The data for water have been corrected for the absorbing contribution of the tank walls. The displacements of the linear portions of the absorption plots are evidence of transition effects to be discussed later in this paper. In Figure 2(b) are shown concrete absorption data obtained with carbon disc detectors using the C 12 (n,2n) C 11 reaction whose threshold is about 20 Mev. |
