Non-linearity in radiocaesium soil to plant transfer: Fact or fiction?

Non-linearity in radiocaesium soil to plant transfer: Fact or fiction?

The basis premise of many radiological assessments is the assumption that the transfer of many radionuclides from soil to herbage and hence animal derived food products is a positive linear relationship for a given set of ecological conditions. However, a number of authors have published results, which they conclude demonstrate non-linear transfer of radiocaesium to plants and animals with tran...

Factors Influencing the Soil to Plant Transfer of Radiocaesium

Radiocaesium isotopes are among the long-lived radionuclides which were released in largest quantities into the environment as a consequence of the atmospheric nuclear weapon tests and accidents involving nuclear material (Chernobyl and Fukushima, etc.). Its transfer to plants, especially those for human or animal food, can be a major pathway for human intake and, therefore, have a significant ...

Sonofusion – Fact or Fiction?

Sonoluminescence and Sonofusion phenomena may occur when vapor bubbles implode. This paper reviews the status of our understanding of the bubble dynamics involved in these interesting phenomena. In particular, the experimental and analytical evidence supporting the observed production of neutrons and tritium due to thermonuclear fusion within imploding bubble clusters is reviewed. Moreover, pot...

NFRs : Fact or Fiction ?

Fact or fiction

Many previous studies have aimed at spermatogenesis of male murine germ cells in vitro, but no efficient system has been established yet that covers the entire process of mammalian spermatogenesis in a culture dish permanently. In this review, we report on the requirements of spermatogenesis and the current state of different culture methods using testicular tissue fragments, single cell suspen...
