Radiation parameters

An order of magnitude higher radiation parameter R was needed than reported in the literature to match the observed migration rate. 

The same is true of the geographical distribution of the uranium concentration in glacial till, the most common soil type in Finland (Geological Survey of Finland, 1985). The sometimes very large effect of ground permeability is the main reason that the details of the radon concentration distribution differ from the distribution of other radiation parameters. 

Since the electron detector is assumed to be insensitive to the electron spin, and the photoelectron has a well-defined parity (< or even), the radiation parameters of the photoelectron are given by (/Cj = 0, and kt = 0 and k1 =2 only, note kx = k in the present case)...

RC rooms should be decontaminated, and the radiation parameters be measiued and mapped. RC power supply should be cut off, and all RC rooms be locked and sealed. 

Simultaneously performed repeated EDR measurements (using GGR-1) in bottom sediments 50-200 m aroimd the submarine also obtained the results within 3-5 pR/h. At a later time (January-December 2004) the RChBPS specialists put to sea more than once. According to the results of their measurements on sea bottom in the submarine sinking area (using GGR-1), the radiation parameters still remained within the background levels. 

Pressure adjustment Varying pressure might preserve scaling of all but radiation parameters. Unfortunately to scale a 1 mile fire to 50 feet would requires use of 1000 atm pressure. 

These equations are commonly called pyrolysis relations, in reference to the thermal (as opposed to a possibly chemical or photonic) nature of the initiating step(s) in the condensed phase decomposition process. It can be seen that while the second, simpler pyrolysis expression with constant coefficient As) preserves the important Arrhenius exponential temperature dependent term, it ignores the effect of the initial temperature, condensed phase heat release and thermal radiation parameters present in the more comprehensive zero-order pyrolysis relation. These terms To, Qc, and qr) make a significant difference when it comes to sensitivity parameter and unsteady combustion considerations. It is also important to note the factor of 2, which relates the apparent "surface" activation energy Es to the actual "bulk" activation energy Ec, Es- E /1. Failure to recognize this factor of two hindered progress in some cases as attempts were... 

A set of at least two cubes are used to achieve the full capability of the instrument. The relative locations of the radiometer cubes and the flare, as well as the orientations of the cubes are determined prior to the flare test and entered into the computer to allow real-time tracking of key flare radiation parameters. Each radiometer on the cubes is connected to a data acquisition system. The data acquisition system collects the data from each sensor and performs trigonometric calculations using a complex set of equations. The results are real-time parameters of the flare radiation total radiation levels from both cubes, incidence angles, and the flare epicenter coordinates. This instrument has three main advantages over the handheld instrument ... 

Neuroradiologists are familiar with factors that affect patient dose such as pitch, milliamperes (mA), kilovoltage peak (kVp), and collimation, but there are additional ways to further reduce radiation exposure. The combination of low kilovolt peak (80 kVp) with low milliamperes-seconds (no more than 200 mAs) has already been noted and is an accepted strategy for dose reduction [36, 87, 88]. (Tube current is directly proportional to dose, but at a cost of increased noise, which is increased by 1/VmA). In our institution, we recently lowered the mAs of our CTP protocol from 200 to 150 mA resulting in 25% dose reduction, previously estimated at 0.47 Gy (the FDA suggests 0.5 Gy as the upper dose limit for a CTP study). Table 5.4 summarizes the radiation parameters of the sample CTP protocol of Tables 5.2 and 5.3. 

The fluorescence lifetime measurements were performed with a streak camera (Agat SF 3M, VNIIOFI, Russia). A Nd YAG laser with excitation wavelengths of 532 and 266 nm (the second and fourth harmonic of fundamental radiation) was used as a light source. The laser radiation parameters of the fluorimeter were as follows (for 532 nm) pulse energy 160 (ij, duration 20 ps (fwhm), beam diameter 5 mm. The error in determining the fluorescence lifetimes in time intervals of several nanoseconds did not exceed 5 %. In addition to the laser equipment, the Cary 100 spectrophotometer (Varian, Inc., USA) and the Cary Eclipse spectrofluorimeter (Varian, Inc., USA slits width was 5 nm) were used for optical density measurements and fluorescence registration, respectively. 

Initially, the radiator dimensions were carried over from a higher power reactor that had 200 m 2 of radiating area. This was an enormously oversized radiator that resulted in the inlet temperature for the reactor being low and the power conversion efficiency high (as high as 37%). To see what effect radiator parameters could have on the core, 4 different sizes of radiator at 5 different thermal power levels were examined. The radiator areas were, from low to high, 80 m 2, 98 m 2, 140 m 2, and 200 m 2. The thermal power levels examined were 200 kW, 250 kW, 300 kW, 350 kW, and 400 kW. Figure... 

A retrospective review of radiation parameters [32] reported details of activity selection method used, actual delivered radiation activity, prior liver treatments, liver lobe or whole liver treated (treated volume), acute and late radiation toxicity and development of RILD, and tumor response in solid tumors affecting the liver. All demographic, tumor, radia-... 

Evaporation models for boiling pools require definition of the leak rate and pool area (for spills onto land), wind velocity, ambient temperature, pool temperature, ground density, specific heat, and thermal conductivity. Radiation parameters (c.g., incoming solar heat flux, pool reflectivity, and emissivity) are also needed if solar radiation is a significant factor. Most of these data arc readily available, but soil characteristics are quite variable.

A scoping analysis of the hot leg piping was performed in ABAQUS to quantify the delay time of external temperature measurement, This model made the same material property assumptions, thermal radiation parameters, and wall thicknesses provided in Reference 9- 77. Additionally, an Inner wall convective heat transfer coefficient from the reactor plant transient model was assigned to provide the model conditions.
