“…Studies in Austria [ 10 , 19 ] reported a broader range in radium activity concentrations and a higher mean value than this study. Studies in Malaysia [ 22 ] and Hungary [ 11 ] reported a very large range for 226 Ra, with some values reported above 3000 mBq/L. For uranium isotopes, the ranges of activities reported in Japanese bottled water in this study were 0.24–24 mBq/L and 0.13–26 mBq/L for 238 U and 234 U, respectively.…”

“…For example, Shiraishi et al investigated the effective dose due to 232 Th and 238 U in imported mineral waters [ 6 ], and Shozugawa analysed four Japanese bottled waters for 134 Cs and 137 Cs following the FDNPP accident in 2011 [ 7 ]. However, no single study has attempted to analyse Japanese bottled waters for a comprehensive suite of radionuclides, although similar studies have been conducted in other countries for estimating the activity concentration and ingestion doses arising from the consumption of natural radionuclides in bottled water [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”

Activity concentrations of 234U, 235U, 238U, 226Ra, 228Ra, 222Rn, 210Po, 210Pb, 40K, 3H, 14C, 134Cs and 137Cs were determined in 20 different Japanese bottled drinking water commercially available in Japan. The origins of the mineral water samples were geographically distributed across different regions of Japan. Activity concentrations above detection limits were measured for the radionuclides 234U, 235U, 238U, 226Ra, 228Ra and 210Po. An average total annual effective dose due to ingestion was estimated for adults, based on the average annual volume of bottled water consumed in Japan in 2019, reported to be 31.7 L/y per capita. The estimated dose was found to be below the recommended World Health Organisation (WHO) guidance level of 0.1 mSv/y for drinking water quality. The most significant contributor to the estimated dose was 228Ra.

While the consumption of seaweed and seaweed-based products is very common amongst East Asian nations, forming a notable component of the daily diet, relatively very few studies have concerned the concentrations of heavy metals in these together with potential effects on human health. The present study analyses the concentrations of 17 elements in locally resourced seaweed, also assessing potential noncarcinogenic and carcinogenic risks. The samples were ground, homogenized, and quantified using the ICP-OES technique. It has been found that the essential elements K, Ca, Mg, Zn, and Na typically show concentrations somewhat greater than a number of potentially toxic metals, in particular, Cd, Pb, Ag, and As, with exceptions being Ni, Cr-VI, and Si. Statistical analysis indicates all of the latter to have similar origin, with increased concentration of these metals within the marine ecosystem. While the daily estimated intake of most metals is seen to be within the daily dietary allowance level recommended by various international organizations, the noncarcinogenic risk shows a value greater than unity, estimated via the hazard quotient. This indicates a potential for adverse effects to health arising from consumption of the sampled seaweed. The carcinogenic risk resulting from nonessential elements shows values greater than the United States Environmental Protection Agency (US-EPA) reference limit of 10−4. Considering the nonbiodegradability of heavy metals and metalloids and their potential accumulation in seaweed, there is need for critical examination of metal levels in the seaweeds obtained from the present study locations, together with the introduction of practices of removal of heavy metals via bio-adsorbent techniques.

“…18 The fitted efficiencies obtained were used in activity determination of samples, following the procedure of Khandaker et al. 19–21 The gamma-ray lines of 351.93 keV (35.6%) from 214 Pb and 609.32 keV (45.49%) from 214 Bi were used to determine the activity concentrations of 226 Ra; the gamma-ray lines of 238.632 keV (43.6%) from 212 Pb and 583.19 keV (85.0%) from 208 Tl were used to determine the activity concentrations of 232 Th following the weighted mean approach. 22 The single gamma-ray line of 1460.822 keV (10.66%) was used to determine the activity concentrations of 40 K.…”

Samples of several brands of tiles popularly used in Bangladeshi dwellings have been evaluated in terms of their efficacy towards shielding of ionizing radiation. These decorative tile samples, differing in material composition, colour, thickness and density, were collected from home and abroad. Using a well-shielded high-purity germanium γ-ray spectrometer, evaluation was made of the attenuation coefficients of the investigated tiles for various photon energies, 59 keV, 661 keV, 1173 keV and 1332 keV. In addition, use was also made of energy dispersive X-ray spectroscopy, both techniques being applied in characterizing dosimetric properties of these tiles. The associated shielding parameters of half-value layer, radiation protection efficiency and effective atomic number (Zeff) were calculated. Among the basic building materials such as brick, concrete, marble, tiles etc., the tiles under study have shown better indices as ionizing radiation shielding materials, being comparable with steel. The Zeff values of the studied tiles are comparable with that of the commercially available dosimeter TLD-200, and thus can be considered a potential material for use in environmental radiation monitoring.
