Special Issue Information

Dear Colleagues,

The presence of pollutants in the environment constitutes a health risk to the population, since this could increase the likelihood of incurring cancer. Experimental analysis will enhance the detection of significant radionuclides and metals that cause harm to the population and stimulate environmental remediation.

Among the various analytical techniques for the assessment of physical and chemical pollutants in the environment, alpha and gamma spectrometry are employed to obtain the specific activity of alpha and gamma radionuclides, respectively; ICP-MS can be used to investigate metals concentration; liquid scintillation counting (LSC) is employed to quantify the activity concentration of tritium, radon, and gross alpha and beta; total alpha/beta counting, with the thick source method, can be used for gross alpha and beta specific activity evaluation; and emanometry, in the H2O setup configuration, can be employed to estimate the gas radon activity concentration.

This study evaluates the concentrations of trace elements (TEs) in soils from the rutile deposit area of Akonolinga, Cameroon, and analyzes the associated health risks. A total of 25 samples were analyzed using flame atomic absorption spectrometry (FAAS). The results show that TE concentrations follow the decreasing order Fe, Ti, Zr, Mn, Cr, V, Ba, Zn, Nb, Ni, Pb, Ga, Cu, Co, Y, Br, and Sn. Pollution indices and the Pearson correlation matrix reveal moderate correlations between Fe and several other TEs, indicating a common origin. Enrichment Factors show significant enrichment in Zr, Nb, and Ti, with notable enrichment in Cr and Co at certain sites. Although the Geo-Accumulation Index indicates no direct contamination and the overall ecological risk is low, the Contamination Factor reveals high levels for Cr, Nb, Ti, and Zr. The carcinogenic risk is moderate, while non-carcinogenic risks are high for children and considerable for adults. These research highlight the potential public health impacts in this mining region and provide essential baseline data for future environmental risk management. Full article

In this paper, the evaluation of the Rn-222 radioactivity content in drinking water samples from the Calabria region, southern Italy, is reported as a case study. The Rn-222-specific activity in the analyzed groundwater samples for human use was evaluated by using the PerkinElmer Tricarb 4910 TR setup and compared with the parameter value (100 Bq L−1) reported in the reference Italian legislation, i.e., D.Lgs. 28/2016, derived from the European Directive 2013/51/Euratom. The radiological health risk for the population of the investigated area, due to the ingestion and inhalation of Rn-222 dissolved in water, was then evaluated by calculating the total annual effective dose, only in those cases where the parameter value was exceeded. The obtained results represent a main reference for the investigated area and are useful for determining any possible radiological health risk for human beings related to the ingestion of the investigated radionuclide. Moreover, they can also be used as a baseline for future investigations regarding background radioactivity levels. Full article

This work presents a review and evaluation of studies measuring exposure to Radiofrequency Electromagnetic Fields (RF-EMF). The review meets the basic quality criteria and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines after the eligibility criteria of the PECO (Population, Exposure, Comparator, and Outcome) methodology and the instrument Critical Appraisal Skills Programme Español (CASPe). A total of 86 papers published between 1 January 1998 and 31 December 2023 are included: 61 studies with spot measurements and 25 studies with mixed methodologies (spot measurements, personal measurements with volunteers or with a trained researcher and prediction models) are highlighted. Forty-three percent of the studies use Spectrum Analyzers in the spot measurements, mainly the Narda SRM–3006, followed by the Narda SRM-3000, highlighting the introduction and use of Sensors for this kind of study. The minimum mean value was measured in Palestine at 0.0600 µW/m2, and the maximum mean value was measured in Norway at 200,000 µW/m2. The RF-EMF exposure levels measured in the different microenvironments are minimal and far from the maximum levels established by the ICNIRP guidelines. Full article
