Israel has lifted its embargo on Apple’s iPads after research showed the wireless signal from the gadget is not powerful enough to disrupt other devices.

Around 10 iPads were seized by security staff at Ben Gurion airport, where they were held for a fee until their owners left the country. It was thought that the devices emit a signal which was too powerful and could interfere with Israeli computers and other devices.

Israel’s Communications Minister Moshe Kahlon said that tests had proved the iPad was safe and imports would now be allowed.

The iPad, which operations like a flat, touchscreen computer, has not yet been launched outside the US. It will be available outside the US to order on May 10.
