大强度微波急性辐照对生理必需要元素的影响取决于辐照强度和作用时间。频率２４５０ＭＨ２、５０ｍＷ／ｃｍ２的微波使兔血清铜明显降低；１００ｍＷ／ｃｍ２致血清铜、铁、铜／锌比值和氯含量显著降低；时间减半的更大强度辐照（２００ｍｗ／ｃｍ２）未致上述元素明显改变。５０和１００ｍＷ／ｃｍ２还致血清锌较照前显著增高，使血清钾较照前显著降低。对元素钙、镁、钠无明著影响。结果表明，血清铜、铁、锌、钾、氯含量和钢／锌比值没变，可作为评价大强度微波影响的指标之一。 The impact of intensive microwave irradiation on physiologically essential elements depends on the intensity of irradiation and the duration of action. The serum copper of 2450MH2 and 50mW / cm2 was significantly decreased. The serum copper, iron, copper / zinc ratio and chlorine content of 100mW / cm2 were significantly reduced. The higher intensity radiation (200mw / cm2) The above elements have changed significantly. 50 and 100mW / cm2 also caused serum zinc significantly higher than before, so that serum potassium was significantly reduced compared with before. The elements of calcium, magnesium, sodium no obvious effect. The results show that serum copper, iron, zinc, potassium, chlorine content and steel / zinc ratio has not changed, can be used as an indicator of the impact of high-intensity microwave.
