Sentence examples for surface radioactivity from inspiring English sources
The experimentally measured ground level atmospheric electrical conductivity is validated from a simplified ion aerosol model for which the inputs are ionization rate from surface radioactivity, aerosol density and meteorological parameters.
Because the absolute value of Rscale probably depends on the extent of the decontaminated area around the GD site as well as on the ratio of the surface radioactivity densities at both sites, comparisons of Rscale values at various places are meaningless.
HeLa cells grown in 12-well dishes were treated with 125I-EGF at 37°C and the ratio of internalized and surface radioactivity was determined during linear 3-min to calculate the specific internalization rate constant ke as described previously [7].
Surface radioactivity (counts per minute per mm) was measured and averaged from three replicate brain slices from each rat using Beta-vision plus software (Biospace Labs).
The temporal variations in the surface 7Be radioactivity in Tokyo exhibit the enhancements in spring and autumn.
The latitudinal production rate at geomagnetic latitude 20 30° (Japan) is 0.023 7Be/cm2 s, indicating ∼1% of cosmic-ray produced 7Be contributes to the surface 7Be radioactivity.
To remove receptor surface bound radioactivity, the cells were then incubated for 10 min with 250 μL of ice cold PMPA solution (10 μM in PBS).
The two primary effects are thus that continental heat flow is proportional to the surface crustal radioactivity in a given region and decreases with time since last major tectonic event (Stein [1995]).
The higher amount of cell surface-bound radioactivity and the prolonged contact with the cell surface resulted in a higher absolute amount of internalized radioactivity.
Intracellular and surface-bound radioactivity increased rapidly during the first 8 h of incubation, reaching near plateau values at 24 h (Figure 2a,b).
Subsequently, each well was gently treated with 1 mL of an ice-cold mildly acidic medium (sodium acetate buffer, pH 4.5) to remove surface-bound radioactivity, and the rinses were collected in tubes (acidic wash).
