Background Investigations: Office of Personnel Management Needs to Improve Transparency of Its Pricing and Seek Cost Savings

Description: A letter report issued by the Government Accountability Office with an abstract that begins "OPM’s reported costs to conduct background investigations increased by almost 79 percent, from about $602 million in fiscal year 2005 to almost $1.1 billion in fiscal ear 2011 (in fiscal year 2011 dollars). However, the extent to which OPM’s cost data are reliable is unknown because an audit of OPM’s revolving fund, which finances business-type operations, has not been conducted. Independent audits of O… more

CO{sub 2} dial transmitter/receiver noise characterization and related correlated noise issues

Description: Our approach concerning the development of hard target return CO{sub 2} DIAL transmitter/receiver systems is two phased- (i) through analysis and experiment, develop a fundamental understanding of the transmitter/receiver physics specific to DIAL systems and (ii) apply these fundamentals in the development of optimal performance DIAL transmitter/receiver systems. We present our progress and results towards these objectives with the following topics addressed: A general overview of the DIAL tran… more

COMPARISON OF NATURAL BACKGROUND DOSE RATES FOR RESIDENTS OF THE AMARGOSA VALLEY, NV, TO THOSE IN LEADVILLE, CO, AND THE STATES OF COLORADO AND NEVADA

Description: In the latter half of 2005, the U.S. Environmental Protection Agency (USEPA) published a Proposed Rule (40 CFR Part 197) for establishing a dose rate standard for limiting radionuclide releases from the proposed Yucca Mountain high-level radioactive waste repository during the time period from 10{sup 4} to 10{sup 6} years after closure. The proposed standard was based on the difference in the estimated total dose rate from natural background in the Amargosa Valley and the ''average annual backg… more

Data Filter Characteristics and Effects

Description: The use of data filters in electronic circuits is normally considered undesirable because filtering irretrievably eliminates desirable as well as undesirable information. Filtering is necessary in some applications, however, to obtain any useful information from measurements made in high-noise and distorted environments and from FM tape-recording and carrier-frequency-type systems. This memorandum discusses related theory and special filter characteristics necessary for retaining the maximum us… more

Evaluation of radioactive background rejection in 76Ge neutrino-lessdouble-beta decay experiments using a highly segmented HPGe detector

Description: A highly segmented coaxial HPGe detector was operated in a low background counting facility for over 1 year to experimentally evaluate possible segmentation strategies for the proposed Majorana neutrino-less double-beta decay experiment. Segmentation schemes were evaluated on their ability to reject multi-segment events while retaining single-segment events. To quantify a segmentation scheme's acceptance efficiency the percentage of peak area due to single segment events was calculated for peak… more

Experimental study of variations in background radiation and the effect on Nuclear Car Wash sensitivity

Description: Error rates in a cargo screening system such as the Nuclear Car Wash [1-7] depend on the standard deviation of the background radiation count rate. Because the Nuclear Car Wash is an active interrogation technique, the radiation signal for fissile material must be detected above a background count rate consisting of cosmic, ambient, and neutron-activated radiations. It was suggested previously [1,6] that the Corresponding negative repercussions for the sensitivity of the system were shown. Ther… more

The High Background Radiation Area in Ramsar Iran: Geology, Norm, Biology, LNT, and Possible Regulatory Fun

Description: The city of Ramsar Iran hosts some of the highest natural radiation levels on earth, and over 2000 people are exposed to radiation doses ranging from 1 to 26 rem per year. Curiously, inhabitants of this region seem to have no greater incidence of cancer than those in neighboring areas of normal background radiation levels, and preliminary studies suggest their blood cells experience fewer induced chromosomal abnormalities when exposed to 150 rem ''challenge'' doses of radiation than do the bloo… more

Neutron measurements of the fuel remaining in the TMI II once-through steam generators (OTSG'S)

Description: Polypropylene tubes containing a string of 18 copper rods were inserted into the lower head region and each J-leg of the two once-through steam generators (OTSG) of the unit two reactor at Three Mile Island. The object was to measure the neutron flux present in those regions and estimate the amount of residual fuel remaining in each OTSG. The neutron flux from any residual fuel induces a radioisotope, /sup 64/Cu, in the copper coupons. The /sup 64/Cu activity is detected by coincidence counting… more

New Measurements of the Cosmic Background Radiation Temperature at3.3 mm Wavelength

Description: We have measured the temperature of the cosmic background radiation (CBR) at 3.3 mm wavelength in 1982, 1983, and 1984 as part of a larger project to determine the CBR temperature at five wavelengths from 12 cm to 3.3 mm (Smoot et al. 1985). The 3.3-mm measurements yield a brightness temperature of 2.57 K with a 1{sigma} uncertainty of 20.12 K. This paper describes the instrument, the measurement techniques, and the data-analysis procedures used. Our result is in good agreement with recent meas… more

Radiation Doses to Hanford Workers from Natural Potassium-40

Description: The chemical element potassium is an essential mineral in people and is subject to homeostatic regulation. Natural potassium comprises three isotopes, 39K, 40K, and 41K. Potassium-40 is radioactive, with a half life of 1.248 billion years. In most transitions, it emits a β particle with a maximum energy of 0.560 MeV, and sometimes a gamma photon of 1.461 MeV. Because it is ubiquitous, 40K produces radiation dose to all human beings. This report contains the results of new measurements of 40K i… more
