“…By calculating the detection efficiencies of solid nuclear track detectors CR-39 (ε CR j , ε 0CR j ) and LR-115 type II (ε LR j , ε 0LR j )usingthecode"SSNTDEαM", and counting the densities of traces recorded on (ρ CR G , ρ LR G ), we can determine the ratio C Th ðÞ =CU ðÞ and then the uranium and thorium contents contained in the samples of thyme studied [37].…”

The purpose of our study is to verify the usefulness of gamma irradiation treatment at low doses (0.25, 0.5 and 1 kGy) combined to vacuum packaging on commercial teas of Thymus satureioides deliberately contaminated with Escherichia coli. The efficiency and the influence of the process on contamination level and the shelf life of the product were studied. The phenolic composition and concentration were identified in the unirradiated and irradiated thyme. The total phenolic content (TPC) was assayed by the Folin-Ciocalteu method, the individual phenolic compounds were determined by high liquid chromatography (HPLC) and the essential oil was characterized by gas chromatography coupled to mass spectroscopy (GC-MS). The plant was observed by scanning electrons microscopy and the radioactivity effect was analyzed. The results show a complete decontamination of thyme depending to the dose and the storage time. Privileged hygienic quality was found in the irradiated thyme with the highest concentrations of polyphenols. The process showed the conservation of thyme quality without any alteration of its characteristics or radioactivity effect.

“…Solid-state nuclear track detection technique is widely used as an effective tool to measure α-tracks activity [1], where SSNTDs have been used in geology [2][3][4][5][6] and environment [7,8]. Both thorium and uranium contents in various natural materials have been determined using SSNTD's active techniques [9].…”

Determination of thorium and uranium contents in soil samples using SSNTD’s passive method

Thorium-to-uranium ratios have been determined in different soil samples using CR-39 and LR-115-II solid-state nuclear track detectors (SSNTDs). A calibration method based on determination of SSNTD registration sensitivity ratio for α-particles of thorium and uranium series has been developed. Thorium and uranium contents of the standard soil samples have been determined and compared with its known values. There is a good agreement between the results of this method and the values of standard samples. The method is simple, inexpensive, non-destructive and has a wide range of applications in environment, building materials and petroleum fields.
