• Abstract:
  This report describes selected biological effects on transformed human cell lines and on rats from exposure to simulated ; maglev magnetic fields (MFs). Rats (n = 6 per group) were exposed at various times throughout the 24-h day to MFs ; simulating the de and complex ac components of the German TransRapid TR-07 maglev prototype vehicle. Expected ride ; times as long as 4 h and MF intensities from 50*1500 mG measured for the TR-07 were tested, up to MF levels predicted ; for superconducting magnet-powered maglev vehicle compartments (1 mG-1.75 G). Maglev-1 ike HF exposures up to 7 times ; the intensity produced by the TR-07 had no effect on cultured growth of four human cell lines or on chemically Induced ; differentiation compared to control, unexposed cultures. Changes in the amount of rat pineal melatonin and serotonin-NacetyI ; transferase (NAT), which have been shown by others to be decreased under a range of eletromagnetfc field (EMF) ; exposure frequencies and intensities, were not observed for TR-07-1 ike MFs. Intermittent exposure to de-component ; maglev MFs (1-2 C) significantly depressed nighttime (control) levels of NAT, with weak effects on melatonin and NAT ; seen with 1- to 2-G-intensity intermittent (ac component alone) and continuous maglev (ac ♦ dc) MF exposures. These ; results should be further examined, since they suggest that ac component TR-07-like MFs and time-varying EMFs at ; superconducting maglev intensities produce biological effects.
