A dedicated ghost hunter has raised health concerns after recording 'off the scale' readings of electromagnetic energy at a public park situated opposite two cemeteries.

Stephen Morgans, 49, took up ghost hunting two years ago after the death of his father when he started experiencing unusual occurrences at his home in Mitcham.

He said: "Things started happened around the house.

"Doors were opening and shutting and I heard footsteps.

"I started buying videos and books because I was so interested in it."

The father of three says he has seen several apparitions during his hunts from a white lady, ghostly monk and Victorian undertaker.

In his latest hunt, the father-of-three made a visit to Rowan Road Recreation Ground, Mitcham and was shocked with the readings from his electromagnetic field (EMF) reader.

Ghost hunters use EMF readers to monitor fluctuations in EMF fields which they believe can indicate a ghost’s presence.

Although Rowan Road Recreation Ground is opposite Streatham Cemetery and Rowan Road Jewish Cemetery the readings are so high Mr Morgans does not believe the cause is supernatural.

He said: "There was so much EMF I was getting a bit concerned because children play there.

"There are two cemeteries across the road but even if 100 ghosts come over it would cause that much EMF because it’s all around the park."

He returned to the park to recheck his reading which were again unusually high.

He said: "The only thing I can think of is during World War Two maybe a few bombs were dropped or maybe there are cables running underneath causing the high EMF readings."

Health concerns over high exposure to EMFs, such as mobile phone radiation and an increase risk of cancer, have been raised but never proven, according to the World Health Organisation.

Others have claimed to suffer with a hypersensitivity to EMFs causing aches and pains, headaches, depression, lethargy, sleeping disorders, but again there is little scientific evidence to support this theory.
