This paper presents the accumulation process of radioactive Cs in edible mushrooms. We here first report the direct accumulation pathway of radioactive Cs from contaminated wood logs to the fruit-bodies of shiitake mushrooms through the basal portion of the stipe. In this pathway, radioactive Cs is not transported through the hyphae. This pathway results in a high accumulation of radioactive Cs...

background: people who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. the aim of this work was to estimate radiation dose received by nuclear medicine nurses. materials and methods: in this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...

he topic of radioactive waste generates debate, both publicly and scientifically. Like chemical and other hazardous waste, radioactive waste needs to be dealt with to ensure its safety and its security. Proper management and disposal of most forms of radioactive waste is technically straightforward. A robust safety regime has been developed internationally for managing and disposing of radioact...

introduction: hyperthyroidism is a relatively common disorder caused by different etiologies. graves’ disease, and toxic-nodular goiter (plummer’s disease) are among the most common causes. treatment with radioiodine is considered to be the treatment of choice in many of the patients. higher biological half-life of ¹³¹i in hyperthyroid patients as compared with patients with differentiated thyr...

purpose: to design and manufacture iodine 125 radioactive plaques which can be used in patients with ocular melanoma, and to evaluate the efficacy of plaques in an animal model. methods: this prospective basic study was performed in collaboration with farabi hospital and tehran atomic energy agency. the iodide 125 plaques were designed and manufactured based on the collaborative ocular melanoma...

Abstract In this chapter we present a very special form of social illusions: unrealistic pessimism (the expectation that negative events will happen to us in comparison others who be less affected by like earthquakes or radioactive pollution). On basis, were interested which illusions, are associated with appearing the moment crisis, appear during eruption COVID-19 pandemic: is, optimism (I per...

Phytoremediation of radioactive waste is a process that uses plants to remove, transfer, or immobilize radionuclides from the contaminated soil, sediment, sludge, or water, and it is a useful method for treating large-scale low-level radionuclide contamination. However, there have not been established criteria which can be utilized to screen out suitable plant species that are capable of remedi...

Introduction: There are natural and artificial radioactive nuclei in our environment, as well as in the structure of the living organism. Currently, industrial and municipal pollution has also an impact on increasing the level of radiation. The present study investigated the effect of inlet water from Arak Wastewater Treatment Plant on international Meighan Wetland and...
