Opis:
Luminescence dating is based mainly on the dosimetric properties of quartz and feldspar. These minerals are among the most popular found on Earth, resulting in the possibility of using luminescence methods in practically any environment. Currently, quartz remains the best recognized mineral in terms of dosimetric properties, particularly with regards to results obtained for quartz grains, which are regarded as being the most reliable in luminescence dating. Supporters of luminescence methods are constantly growing, however, these groups do not always have sufficient knowledge to avoid even the most basic of issues that may be encountered overall – from the process of sampling through to the awareness of what a single luminescence result represents. The present paper provides an overview of several practical aspects of luminescence dating such as correct sampling procedures and all necessary information regarding the calculation of the dose rate and equivalent dose with particular reference to potential problems that occur when the age of the sample is being determined. All these aspects are crucial for obtaining a reliable dating result, on the other hand, they remain a potential source of uncertainty.

Opis:
This work presents a comprehensive study of natural radioactivity in building materials used in Iran. For this purpose, 177 samples of five types of building material, i.e. cement, gypsum, cement blocks, gravel and brick, were gathered from different regions of the country and analyzed by gamma spectroscopy to quantify radioactivity concentrations using a high purity germanium (HPGe) detector and a spectroscopy system. According to the results of this investigation, cement samples had maximum values of the mean Ra-226 and Th-232 concentrations, 39.6 and 28.9 Bq/kg, respectively, while the lowest value for mean concentration of these two radionuclides were found in gypsum samples 8.1 and 2.2 Bq/kg, respectively. The highest (851.4 Bq/kg) and lowest (116.2 Bq/kg) value of K-40 mean concentration were found in brick and gypsum samples, respectively. The absorbed dose rate and the annual effective dose were also calculated from the radioactivity content of the radionuclides. The results show that the maximum values of dose rate and annual effective dose equivalent were 53.72 nGy/h and 0.37 mSv/y in brick samples. The radium equivalent activities Req calculated were below the permissible level of 370 Bq/kg for all building materials. The values of hazard indexes were below the recommended levels, therefore, it is concluded that the buildings constructed from such materials are safe for the inhabitants. The results of this study are consistent with the results of other investigations in different parts of the world.

Opis:
Objectives Mammographic density (MD) refers to the percentage of dense tissue of an entire breast and was proposed to be used as a surrogate marker for breast cancer. High-dose ionizing radiation (IR) has been recognized as a breast cancer risk factor. The aim of our study was to investigate association between lifetime low dose ionizing radiation (LDIR) and MD. Material and Methods A cross-sectional study included 467 women aged 40–60 years who underwent screening mammography in Łódź, Poland. The digital mammography examination of the breasts included both craniocaudal and mediolateral oblique views. The volumetric breast density (VBD) (%) and fibrograndular tissue volume (FG) (cm3) were determined based on the analysis of mammographic image (“for processing”) using Volpara Imaging Software. The exposure to IR was estimated for each individual, based on the data from interviews about diagnostic or therapeutic medical procedures performed in the area of the neck, chest, abdomen and spine, which involved X-rays and γ rays and the data about the doses derived from literature. Linear and logistic regression were fitted with VBD and FG as the outcomes and organ breast dose, effective dose and number of mammographies as the determinants, adjusted for major confounders. Results The analyses showed no association between VBD or FG and the breast organ dose or the effective dose. The only significant finding observed concerned the association between the number of mammographies and the FG volume with β coefficient: 0.028 (95% CI: 0.012–0.043), and predicted mean FG volume >13.4 cm3 among the women with >3 mammographies when compared to those with none. Conclusions This study does not, in general, provide support for the positive association between LDIR and MD. The weak association of the FG volume with the number of mammographies warrants further verification in larger independent studies.

Opis:
In this work attempts have been made to investigate the variation of polystyrene calorimeter response after frequent irradiations with an electron beam. Polystyrene calorimeters are routinely used in every radiation processing center as a traceable to NPL primary standard dosimeter. Thus, self designed high impact polystyrene as the calorimeter core was irradiated several times up to many thousands of kGy doses. After each irradiation, the specific heat capacity of the polystyrene as the main changeable parameter was measured using the differential scanning calorimeter system (DSC) in the practical temperature range of polystyrene calorimeter. Therefore, correction factors to calculate the precise absorbed dose were obtained. At the final stage, several these calorimeters were irradiated simultaneously along with two Risoe standard calorimeters and another correction factor for each tested calorimeter was calculated.

Opis:
Medical exposure for abdomen radiography is associated with higher doses compared to X-Rays of the chest and other extremities. The study aims to determine the mean entrance skin dose (ESD) for 104 adult patients between 20-89 years with 2 X-Ray units (A and B) in Aba, South-East Nigeria and to determine the ESD at the 75th percentile to estimate the local diagnostic reference levels (LDRLs). This study also determined the effective dose (E), the dose area product (DAP) and the relationship between absorbed dose (DT) and other parameters. This study will also compare its findings with relevant articles where necessary. The study used 2 functional floors mounted X-Ray units. A total of 208 annealed thermoluminescent dosimeters (TLDs) were used made of Lithium Fluoride, doped with Magnesium and Titanium (LiF: Mg, Ti). Two TLD chips were used per patient. The chips were positioned at the anterior and posterior end of the patient respectively for a given beam area for abdomen radiography. After exposure, a calibrated RadPro TLDcube 400 reader (Freiberg Instrument, Germany) was used to estimate individual patient doses. This was done by multiplying the TLD counts by a pre-determined calibration factor (CF). The mean/75th percentile ESD for facilities A and B was 2.92/4.12 and 3.01/3.67 mGy. The E for facilities A and B was 0.73 and 0.82 mSv respectively. There was a good relationship between the DT with ESD, exit dose (ED) and DAP for facility A, but no relationship was seen with other parameters. The mean ESD was lower compared to the National Council on Radiation Protection and Measurements (NCRP 172) and the American Association of Physicists in Medicine (AAPM) reports respectively. The study proved useful and could serve as a reference point to initiate LDRLs within the South-East zone in Nigeria for abdomen radiography.

Opis:
Objectives The study aim was to analyse the influence of the lead free cap on doses received by interventional cardiologists. The impact of lead free cap on doses to the head were evaluated in number of studies. As different methods used to assess the attenuation properties of protective cap can lead to ambiguous results, a detailed study was performed. Material and Methods The effectiveness of a lead free cap in reducing the doses to the skin was assessed in clinic by performing measurements with thermoluminescent dosimeters attached inside and outside the cap first during individual coronary angiography (CA) or CA/percutaneous transluminal coronary angioplasty (CA/PTCA) procedures and then cumulated during few procedures of the same type. In order to investigate the effect of the cap on reducing the doses to the brain additional measurements were performed with a male Alderson Rando and polymethyl methacrylate (PMMA) phantoms representing the physician and the patient, respectively for different projections. The brain dose per procedure, annual and cumulated during entire working practice were estimated for both cases working with and without the cap. Results The dose reduction factor (RF) for the skin (the quotient of doses outside and inside the cap) vary from 1.1 up to 4.0 in clinical conditions; on average 2.3-fold reduction is observed in the most exposed left temple. The RFs determined for the part of the head covered by the cap range from 1.4 to 1.8 while for the brain from 1.0 to 1.1 depending on the projection. The estimated annual brain dose for interventional cardiologist performing yearly 550 CA/PTCA procedures without any protective shields is 7.2 mGy and it is reduced with the lead free cap by an average factor of 1.1. Conclusions The study results proved the considerable effectiveness of lead free cap to protect the skin but very limited to protect the brain.

Opis:
Nowadays in radiotherapy, much effort is taken to minimize the irradiated volume and consequently minimize doses to healthy tissues. In our work, we tested the hypothesis that the mean dose distribution calculated from a few fi rst fractions can serve as prediction of the cumulated dose distribution, representing the whole treatment. We made our tests for 25 prostate cancer patients treated with three orthogonal fi elds technique. We did a comparison of dose distribution calculated as a sum of dose distribution from each fraction with a dose distribution calculated with isocenter shifted for a mean setup error from a few fi rst fractions. The cumulative dose distribution and predicted dose distributions are similar in terms of gamma (3 mm 3%) analysis, under condition that we know setup error from seven fi rst fractions. We showed that the dose distribution calculated for the original plan with the isocenter shifted to the point, defi ned as the original isocenter corrected of the mean setup error estimated from the fi rst seven fractions supports our hypothesis, i.e. can serve as a prediction for cumulative dose distribution.

In this work, the authors investigated the influence of proton-irradiation on the dark current of XBp longwave infrared InAs/GaSb type-II superlattice barrier detectors, showing a cutoff wavelength from 11 μm to 13 μm at 80 K. The proton irradiations were performed with 63 MeV protons and fluences up to 8∙10¹¹ H+/cm² on a type-II superlattice detector kept at cryogenic (100 K) or room temperature (300 K). The irradiation temperature of the detector is a key parameter influencing the effects of proton irradiation. The dark current density increases due to displacement damage dose effects and this increase is more important when the detector is proton-irradiated at room temperature rather than at cryogenic temperature.

Opis:
Measurements of the short-lived radon progeny particle size distributions were performed under realistic natural conditions in 54 dwellings in 6 regions of Poland by means of the Radon Progeny Particle Size Spectrometer (RPPSS). The RPPSS comprises a one open face stage, a 4-stage diffusion battery and a 3-stage multi-hole inertial impactor. It was manufactured at the ARPaNSA (Melbourne, Australia), under supervision of Dr S. B. Solomon and supplied with his software. While using the continuous mode, the programme provides analysis of the potential alpha energy concentration on each stage, particle size distributions and weighted dose conversion factors based on the ICRP human respiratory tract model (HRTM) as implemented in the computer code RADEP (radon dose evaluation program). The unattached fraction indoors ranges from ca. 0 to 53% with an arithmetic mean and median of 17%. The equilibrium factor F was observed in the range from 7 to 64% with an arithmetic mean of 32% and median of 29%. The annual effective doses from radon progeny for the general population were estimated according to two models: epidemiological and dosimetric. The mean values of the ratios of the dosimetric to epidemiological dose estimates for the general population (breathing rate 0.78 m3/h) and workers (breathing rate 1.2 m3/h) are 1.0 and 1.4, respectively. The epidemiological dose estimates for the general population are smaller in comparison with the dosimetric estimates for the unattached fraction fp greater than 17%. It was shown that the dependence of the ratio of the doses estimated on the basis of two models on the unattached fraction fp is well described by a linear equation.

Opis:
The aim of radiotherapy is to maximize the dose applied to the tumor while keeping the dose to the surrounding healthy tissue as low as possible. To further enhance dose to a tumor, techniques to radiosensitization of the tumor, using high atomic number elements, have been proposed. The aim of this study was to investigate the influence of using gold nanoparticles as a contrast agent on tumor dose enhancement when the tissue is irradiated by a typical mono energy X-ray beam. To improve the conventional radiotherapy enhancement of the absorbed dose in a tumor tissue and to spare the skin and normal tissues during irradiation in the presence of concentration agent, a model based on a Monte Carlo N-Particle eXtended (MCNPX) computer code has been designed to simulate the depth dose in a phantom containing an assumed tumor. Test was carried out in two phases. In phase 1, verification of this model using the MCNPX was evaluated by comparing the obtained results with those of the published reports. In phase 2, gold was introduced into assumed tumor inside the phantom at different depths in the simulation program. Simulation was performed for four different concentrations of gold nanoparticles using a low mono-energetic parallel beam of synchrotron radiation. The obtained results show that the optimum energy for dose enhancement is found to be around 83–90 keV for all gold concentrations. The dose enhancement factor is increased linearly with concentration and diminished in depth along the central beam in the tumor. This approach of introducing contrast agents in conventional radiotherapy could hopefully prepare new treatment planning and improve the efficiency of tumor therapy.
