Validity of surrogates for determination of 30-1000 Hz magnetic field exposure for video display terminal users in office settings.

abstract：:The hypogeomagnetic field (HGMF; magnetic fields <200 nT) is one of the fundamental environmental factors of space. However, the effect of HGMF exposure on living systems remains unclear. In this article, we examine the biological effects of HGMF on the embryonic development of Xenopus laevis (African clawed frog). A ...
