Cell phone radiation throws plants, vegetables in disarray

Posted on

Researchers from Kolkata’s Jadavpur University have indicated mobile-tower radiation affects plants and vegetables, adding to a debate on the health implications of such technology as India’s telecom watchdog tries to dispel fears.

Scientists from the university’s electronics and telecommunications engineering department conducted tests on plants, fruits and vegetables by exposing them to radiation from cell phones.

“Nearly 50 chilli plants exposed to mobile radiation from the seedstage till they grew into plants, attained more height and grew longer leaves than their counterparts not exposed to radiations. However, their, leaves were wrinkled and looked dull compared to normal plants,” said Bhaskar Gupta, professor of electronics and telecommunication at Jadavpur University who led the study.

Alarmed JU researchers have tied up with biologists at the Indian Institute of Science Education and Research. Talks are also on with botanists of other universities, including Calcutta University.

“Our experiments only reveal plants are affected by mobile radiations. We are taking the help of biologists to find out what changes are going on inside plants and whether these are harmful or beneficial. We have proposed a joint study with IISER-biologist Amirul I Mallick and have applied for funding from department of science and technology,” Gupta said.

Since 2012, JU researchers have conducted tests on how radiation from mobile towers and cell phones affect fruits such as guava, grapes, apple, coconut, and flowering plants such as jasmine, nayantara and chilli plants.

“In one study we had taken two pots and had sown chill seeds in both. One pot was kept very close to a cell phone used every day in various modes. Data on the growth of plants was collected over a span of 50 days,” said Ardhendu Kundu a researcher. The handset was used to make calls for more than 17,000 minutes over 50 days. It was kept on standby mode for 54,818 minutes. The mobile rang for around 126 minutes. It was in the call setup mode for nearly 10 minutes.

“Only 50% of the seeds exposed to radiation germinated compared to more than 75% of unexposed seeds. The exposed seeds also took longer to germinate. But surprisingly when the plants, in the exposed pot, started growing they attained more height,” said Kundu.

In another experiment on jasmine plants, researchers saw leaves exposed to radiation allowed more sunlight to pass. They said this could have several connotations, such as the leaf losing density or degrading chlorophyll content.

Though hundreds of studies have investigated how radiations affect humans, there have been few studies on plants. The department of science and telecommunication funded a few studies but their results aren’t out. India is among the fastest growing telecom markets in the world. The Indian telecom industry has grown from a tele-density of 3.58% in March 2001 to 78.13% in February, 2015.

Telecom towers are critical installations. The success of government initiatives such as Digital India, Smart Cities and right to Broadband depends on this infrastructure.

“Problems are aggravating because some telecom companies, in a bid to reduce the cost of their operations, share a single tower. Sometimes a single tower caters to at least four–five providers. This only leads to cumulative radiation effect and could aggravate conditions,” said Sujoy K Guha, director of school of medical science and technology at IIT Kharagapur.
