Different biological effectiveness of ionising and non-ionising radiations in mammalian cells

[摘要] It has been discussed ever since among the scientific communities, whethernon-ionising radiation can alter or harm biological systems. While themechanisms of underlying effects of ionising radiation are well understoodand described here, there is less understanding in the effects caused bynon-ionising radiation except for heating effects. Recent results have beeninterpreted, that numerical chromosome aberrations may be induced byexposure to RF radiation. Our own experiments employing the µTEM cellyield results similar to findings observed for aneugenic-inducing chemicalagents which can cause spindle disturbances. For comparison purpose to theeffects caused by those agents we used the well established human-hamsterhybrid (A_L) cell line to evaluate the biological effects after exposureto RF radiation (835 MHz).
