Outside Earth’s protective atmosphere, there is nothing to shield astronauts from the dangerous cosmic radiation of space.
Space missions are dangerous. But when it comes to long missions, radiation may be the greatest threat to astronauts’ health.
The scientific consensus is that 5G doesn’t pose a danger to our health.
Should we be concerned about the health effects of 5G? The short answer is no – there’s no substantiated evidence that the electromagnetic energy used by mobile telecommunications causes harm.
