Bulk etch characteristics of colorless LR 115 SSNTD
The colorless LR 115 solid-state nuclear track detector (SSNTD) (from DOSIRAD) is based on cellulose nitrate and was first studied in view of its applicability in radiobiological experiments with alpha particles. In this paper, the bulk etch characteristics were studied. We first showed that the shape of the alpha-particle tracks are irregular with blurred contours under the optical microscope....
متن کاملE ects of stirring on the bulk etch rate of LR 115 detector
The e ects of stirring on the bulk etch rate of LR 115 detector has been investigated. The surface pro6le measurement method using an instrument called Form Talysurf has been used to measure the thickness of the active layer of the LR 115 detectors. The etchant was 10% aqueous solution of NaOH maintained at 60◦C. The bulk etch rate under magnetic stirring has been found to be 6:65 ± 0:34 m h−1 ...
متن کاملMeasurement of bulk etch rate of LR 115 detector with atomic force microscopy
Equations for calculating track parameters have been proposed, which invariably involve the track etch rate Vt and the bulk etch rate Vb. The present study measured Vb for the LR115 solid-state nuclear track detector using atomic force microscopy (AFM). The detectors were partially masked using rubber cement and then etched in 2:5 N NaOH solution at 60◦C for time periods ranging from 5 to 40 mi...
متن کاملLong-term determination of airborne radon progeny concentrations using LR 115 solid-state nuclear track detectors
This paper described the establishment of lognormal distributions for the Jacobi room model parameters with a view to improve an existing method for long-term passive measurements of the equilibrium factor using LR 115 solid-state nuclear track detectors, namely, through the proxy equilibrium factor (Fp) method. Fp is defined as (C1 þ C3)/C0 where C0, C1 and C3 are the concentrations of 222Rn, ...
