Effect of rf emf on growth of lepidium sativum

And the answer was Cress. While this study did test the effects of Wi-Fi on other plants broccoli, red clover, and peas and purported to find negative effects on them, science is still waiting for a successful replication to the Danish cress study as well as a replication of new results presented in this paper.

Give them the same amount of water and sun over 12 days, and remember to expose half of them to mobile [Wi-Fi] radiation. Foreign researchers are extremely excited for a biology project from five 9th grade girls … Take Cress seeds and place them into 12 trays.

Although anti-technology sites continue to present the claim as novel and credible, seasoned researchers almost immediately identified significant flaws in the methodology.

He is well known for having unsubstantiated ideas of negative health effects of radiation. A study published in March has been widely billed as a replication of the Danish high school project.

It is a recipe for a biology test so brilliant that it has attracted international attention among acknowledged biologists and radiation experts. Therefore, the girls had to find an alternative. Added further information about a study billed as a replication of the original Danish finding.

There was no difference in germination or biomass at the end of the day experiment. Of the four species we tested, garden cress Lepidium sativum seemed to be the least sensitive to Wi-Fi radiation under controlled laboratory conditions.

And the result spoke was clear: The claim behind a school science project purportedly documenting that wireless signals wilt cress plants remains unproven. Six trays of seeds were put into a room without radiation, and six trays were put into another room next to two [Wi-Fi] routers.

The lack of an apparent biophysical mechanism of interaction and the generally negative results of other studies using RF exposures at similar levels as Wi-Fi Jauchem ; Habash et al.

Do WiFi Signals Stunt Plant Growth?

Then place six trays in two rooms at the same temperature. Such routers broadcast the same type of radiation as an ordinary mobile. After a not so convincing first experiment, Wageningen University started a follow up, of which we never heard again.

We did not get the same results as the high schools students in Denmark. Who are the scientists who are so enthusiastic about this poor study?

Updated [6 November ]: Behind the experiment are five girls from 9b in Hjallerup School in North Jutland, and it all started because they found it difficult to concentrate during the school day … The school was not equipped to test the effect of mobile phone radiation on them.

Most versions of the story did not provide any further detail.Claim: A group of Danish students proved that Wi-Fi signals harm human health in a study involving routers and cress ultimedescente.comen.
