“…Figure 4 shows the values of specific activities of 226 Ra in the phosphogypsum from some countries compared to the average value of 226 Ra in this study. The values of 226 Ra in the phosphogypsum from Egypt [9], Croatia [10], Jordan [11], Slovenia [12], Spain [13], Greece [3], Serbia [14]are higher compared to the results of this study.…”

“…Phosphogypsum is a waste product in the fertilizer industry, generated in the process of producing phosphoric acid from the phosphate ore [2,3]. It contains natural radionuclides from the 238 U and 232 Тh chains as well as 40 К originating from the phosphorous ore but with a disrupted ratio due to the technological process itself [4].…”

The production of phosphoric acid from natural phosphate ore generates an industrial waste product named phosphogypsum. Phosphogypsum contains considerable amounts of natural radionuclides from the 238U chain, originating from the ore but enriched during the technological process. In order to perform radiological characterization of the “HIV” (Chemical Industry Veles) phosphogypsum stockpile, five phosphogypsum samples were collected and analyzed. The mean values of gross alpha and beta specific activities ± standard deviation values were: (950±104) Bq/kg and (1694±220) Bq/kg, respectively. Further analysis showed increased gross activities of radionuclides of the 238U chain, while the radionuclides of the 232Th chain and 40K were below the detection limit. The mean values of the specific activities of 238U and 226Ra were (360±55) Bq/kg and (280±84) Bq/kg, respectively. The estimated annual outdoor effective dose, at 1m received by adults was 0.25 mSv/y, which is below a dose limit of 1 mSv/y for members of general public. The results obtained in this study show that radionuclides, although present in relatively high concentrations in the phosphogypsum pile, do not imply an increased external radiation risk for members of the population. The possible use of phosphogypsum in civil construction and agriculture may not be excluded if conditions of prior good planning taking into account the radionuclides activities exist.

Analysis of the mechanical strength, structure and possibilities of using waste phosphogypsum in aluminum powder composites

et al. 2019

View full text Add to dashboard Cite

This paper presents the results of research on the effect of hydrated calcium sulfate (phosphogypsum) on the mechanical properties of composite based on aluminum powder. The phosphogypsum used is a by-product obtained in the phosphate fertilizers industry, e.g., at the Gdańskie Zakłady Fosforowe "Fosfory. " The amount of phosphogypsum produced in Poland must be reduced due to the high costs of its storage and environmental protection. One of the ways to dispose of it is to use it as a filler in composite rods based on aluminum powder. The amount of phosphogypsum added was 2% and 5% by weight in relation to the aluminum powder's weight. The filled composite was subjected to strength tests to show whether phosphogypsum improves the mechanical properties of aluminum rods. Based on the results obtained, it was revealed that phosphogypsum used as a filler causes similar changes in the mechanical properties as mineral fillers described in the literature. Based on analyses of market potential, it can be easily assumed that there is a significant demand for the results of research on the use of phosphogypsum. The end of the article summarizes the discussed issue, emphasizing that solutions are sought for the use of phosphogypsum.
