Frog spermatozoa, fertilized eggs (during second meiotic division), and embryos (during cleavage) were subjected separately to 30 MHz continuous wave NMR exposure in a static magnetic field of 7.05 kG for 20 min and were compared to unexposed groups, at similar stages, with respect to damage in genetic material, interference with meiotic cell division, and impairment in the development of embryos. No significant differences were observed following treatment suggesting that NMR exposure, at the dose used, does not cause detectable adverse effects in this amphibian.
将青蛙精子、受精卵（处于第二次减数分裂期）和胚胎（处于卵裂期）分别置于7.05千高斯的静磁场中，用30兆赫连续波核磁共振进行照射20分钟，然后将其与处于相似阶段的未照射组在遗传物质损伤、减数分裂细胞分裂干扰以及胚胎发育受损方面进行比较。处理后未观察到显著差异，这表明在所使用的剂量下，核磁共振照射不会对这种两栖动物造成可检测到的不利影响。
