Cress Science Fair Experiment – Mentor College, Mississauga

  • 0 Comments

This grade 7 science experiment studied the impact of radiofrequency radiation from a router on plant growth.  Results showed a negative or slowing effect on growth when closest to the router; therefore, there could be a similar effect on human health or growth.  The American Academy of Environmental Medicine has been studying the effects of non-ionizing radiation such as radiofrequency which includes Wi-Fi (as in this experiment), cell phones and Smart Meter wireless communication.  The problem has been that most studies have looked at thermal effects on health.  However, this plant experiment’s results could show that non thermal radiofrequency radiation exposure causes something to halt the normal growth or development of humans.   All humans on earth would benefit from this knowledge because it could cause people to lessen their radiofrequency exposure to cell phones or Wi-Fi routers; therefore, lessening negative health effects.

Questions Posed

  1. If humans stay more than 300cm away from a direct source of radiofrequency radiation, will their health not be affected negatively?
  2. Would the same results be achieved if testing the effect of radiofrequency radiation on existing, mature plants?
