The thickness of the removed layer of the LR-115-II solid state nuclear track detector during etching is measured directly with a rather precise instrument. Dependence of bulk etching rate on temperature of the etching solution is investigated. It has been found that the bulk etching rate is 3.2 µm/h at 60 • C in 2.5 N NaOH of water solution. It is also found that the track density in detectors exposed to soil samples increases linearly with the removed layer.

“…At the locations in the tissue sample where 10 B is present an ␣-particle and 7 Li-ion are emitted and cause damage to the nuclear detection film. After irradiation the tissue sample is removed from the film and the image of the 10 B-distribution is obtained by chemical etching in a dilute NaOH solution [72]. The distribution of the tracks in the detector is representative of the macroscopic distribution of the 10 B-atoms in the sample.…”

“…At 25°C, the growth had represented as exponential but at higher temperature the growth was not exponential and there was a saturation effect for larger normality. Enge et al (1974) also have shown in their studies on bulk etch rate for cellulose nitrate films, that a saturation on V b is attained beyond 3 N NaOH solution.…”

“…Enge et al [5] hypothesized that a colloid layer of partially dissolved cellulose nitrate molecules together with components of the etching solutions adhered to the surface of the plastic during the etching process. They studied the effects of stirring speed on cellulose nitrate for NaOH at 50°C and found that the bulk etch rate increased with the stirring speed for a constant normality of NaOH, which could be explained by washing off the colloid layer.…”

:In view of the fact that the radon progeny contribute the highest to the natural radiation dose to general populations, large scale and long-term measurements of radon and its progeny in the houses have been receiving considerable attention. Solid State Nuclear Track Detector (SSNTD) based systems, being the best suited for large scale passive monitoring, have been widely used for the radon gas (using a cup closed with a semi-permeable membrane) and to a limited extent, for the measurement of radon progeny (using bare mode in conjunction with the cup). These have been employed for radon mapping and indoor radon epidemiological studies with good results. In this technique, alpha tracks recorded on SSNTD films are converted to radon/thoron concentrations using corresponding conversion factors obtained from calibration experiments carried out in controlled environments.The detector response to alpha particles depends mainly on the registration efficiency of the alpha tracks on the detector films and the subsequent counting efficiency. While the former depends on the exposure design, the latter depends on the protocols followed for developing and counting of the tracks. The paper discusses on parameters like etchant temperature, stirring of the etchant and duration of etching and their influence on the etching rates on LR-115 films. Concept of break down thickness of the SSNTD film in spark counting technique is discussed with experimental results. Error estimates on measurement results as a function of background tracks of the films are also discussed in the paper.
