Mayo-Belwa Local Government Area has been reported to have deposits of Uranium; hence this study was carried out to measure radionuclide activities in Mayo-Belwa soils and to monitor their potential impact on human health. Soils from a depth of 10 cm were collected from each location, using CANBERA NaI (Tl) detector, the activity concentration of radionuclides of 10 soil samples was measured. The radionuclide concentration ranged between 72.7069 - 116.8504 Bq.kg−1 for 238U (measured by 226Ra activity), 148.9168 -981.4994 Bq.kg−1 for 40K and 22.3332 - 108.5203 Bq.kg−1for 232Th. The gamma absorbed dose rate, annual effective dose rate, ranged between 61.3932138.1076 nGyh−1 , 0.0830 - 0.211 mSvy−1 with mean values of 95.1762 ± 21.5257 and 0.1216±0.0359 respectively. The values obtained were compared with the reported data from UNSCEAR, 2000 and ICRP 2005. The excess lifetime cancer risk ranged between 0.00026-0.00061 with an average value of 8.44×10−4. The gamma, internal and external hazard indices ranged between 0.4631-1.0975, 0.5969- 0.9978 and 0.3601-0.8087 respectively. However, dose rates recorded in all locations were above the 60 nGyh−1 recommended limits by UNSCEAR 2000. Furthermore, Ganglare had a gamma index above 1, implying a significant radiation hazard. Also, the average excess lifetime cancer risk (ELCR) of 0.844 × 10−3 was relatively high (t < 0.05) and compared to the world average value of 0.29 ×10−3. With the help of this study, we were able to establish the fundamental facts about the levels of radioactivity and related radiological dangers that exist in the soil of Mayo-Belwa Local Government.

“…Zato je pojam nedostatka proizvoda relativna, a ne apsolutna kategorija, koja u zavisnosti od relevantnih okolnosti svakog pojedinačnog slučaja poprima različitu sadržinu, pa je sud taj koji, u svakom konkretnom slučaju, istupa u ime javnosti i procenjuje kada određeni proizvod ne pruža bezbednost koja se s pravom može od takvog proizvoda očekivati. 43 Takođe, kada procenjuje da li proizvod ima nedostatak, sud nije vezan svrhom koju je proizvođač namenio proizvodu, već upotrebom za koju se razumno moglo očekivati da će proizvod biti korišćen. 44 Takođe, Sud je pozivajući se na istu presudu zaključio da treba primetiti da su određeni proizvodi sami po sebi nebezbedni, ali da to ne znači da su nužno proizvodi s nedostatkom -npr.…”

Zaštita Kolektivnih Interesa Potrošača

View full text Add to dashboard Cite

Za organizovanje jednog efikasnog zdravstvenog sistema od izuzetnog su značaja prilikom pružanja zdravstvenih usluga razvoj medicinske tehnologije i savremena medicinska sredstva. Danas se medicinska sredstva masovno proizvode i imaju karakter proizvoda. U ovom radu autorka kroz analizu odluke zbog štete izazvane upotrebom medicinskog sredstva, Colin Gee and others v. Depuy International Limited, pokazuje da je za pacijente izuzetno važno da im, kao slabijoj strani u postupcima pokrenutim zbog utvrđivanja nastale štete po život i zdravlje, bude omogućen što širi dijapazon mehanizama pravne zaštite kao što je između ostalog i mogućnost kolektivnih tužbi. Autorka smatra da bi trebalo da po uzoru na većinu država članica EU i Republika Srbija još jednom uloži napor i pokuša da uredi kolektivne mehanizme preventivne i kompenzatorne zaštite potrošača i drugih nosilaca kolektivnih interesa. Tako bi, u slučaju da dva ili više pacijenta imaju isti ili sličan činjenični i/ili pravni osnov tužbenih zahteva, i ukoliko pretrpe štetu izazvanu istom protivpravnom radnjom ili upotrebom istog medicinskog sredstva, kolektivni zahtev za naknadu štete mogli da podnesu zajedno. To bi bio način da se inače težak položaj pacijenta u postupcima za naknadu štete bar malo olakša zato što podnošenje pojedinačne tužbe kao inicijalnog akta za pokretanje postupka na prvom mestu znači dosta troškova, odsustvovanje sa posla, angažovanje advokata, kupovinu lekova, rehabilitaciju i slično, što oštećenog dovodi u posebno težak položaj. Parnice ove vrste po pravilu dugo traju, često se izvodi i po više veštačenja, što za pacijenta predstavlja veliki, kako fizički i psihički tako i materijalni teret. Sama mogućnost intervencijskog dejstva presude kod kolektivne zaštite prava i interesa građana omogućila bi većem broju pacijenata efikasniji pristup pravdi i značajno olakšala njihov procesni položaj, što bi za pacijente već oštećenog zdravlja predstavljalo značajnu pomoć.

“…However, such effects depend on several factors, with the dose rate and the linear energy transfer (LET) of the radiation being the most important. The dose rate is the delivery of dose per unit time and the absorbed dose is typically measured in Grays, Gy, where 1 Gy = 1 J/kg [ 10 ]. The higher the dose rate, the greater the cell damage.…”

“…However, based on the radiation protection principles in the EU, controls are recommended for building materials contributing to overall dose by the value of 0.3–1 mSv/y [ 14 ] which corresponds to Iγ = 0.5–1 for bulk materials. Besides the activity concentration index, several others have been developed over the years to evaluate the radiation exposure due to building material, e.g., alpha index [ 10 ], indoor and outdoor hazard indices [ 15 ], different dose parameters [ 16 , 17 , 18 ]. Several studies have been presented concerning the natural radioactivity of building materials [ 19 , 20 , 21 , 22 , 23 , 24 ], based on which it can be concluded that conventional building materials do not pose a radiological hazard due to gamma radiation and rarely exceed the EU annual dose criterion for radiation protection.…”

The paper investigates a possible hazard originating from natural radionuclides in building materials in a selected historical building being reconstructed for housing. Both outdoor and indoor risks were evaluated through the radiological indices and estimated doses, based on measured activities of natural radionuclides in stone and brick materials of the building. The average measured activity concentrations of radionuclides were 7.32 Bq/kg for 226Ra, 40.05 Bq/kg for 232Th, and 546.64 Bq/kg for 40K radionuclides. The average total activity concentration in building materials (594.0 Bq/kg) exceeded the world average value. A correlation was found between the potassium content in the building material samples and the total activity of radionuclides. The gamma indices, Iγ, calculated for the samples, ranged in an interval of 0.26–0.60, not exceeding the restricted limit for bulk materials Iγ = 1. The average annual effective dose due to building materials was 0.53 mSv/y, which does not exceed the limit (1 mSv/y), however, it contributes to a gamma dose excess that is higher than recommended (0.3 mSv/y at the most). The bricks were responsible for a higher level of natural radiation than natural stone material. Nevertheless, based on the radiation protection requirements, it can be concluded that the building can be used for residential purposes after the reconstruction, as no significant human health impact is expected due to the radioactivity of building materials.
