There are two types of radiationthat may be associated with health risks. These are:
You'll usually only be exposed to man-made ionising radiation during certain medical tests, but the levels are so low that the chances of problems developing are small.
Radiation is a general term that refers to any sort of energy that can travel through space either as a wave or a particle.
There are two types of radiationthat may be associated with health risks. These are: non-ionising radiation (low energy) ionising radiation (high energy) You'll usually only be exposed to man-mad
Examples of non-ionising radiation include: ultraviolet radiation visible light infrared radiation microwaves radio and radar waves wireless internet connections (wifi) mobile phone signals
The low levels of radiation you are exposed to during medical tests can be measured in units called millisieverts (mSv). Some examples of different levels of radiation exposure are listed below. a
There's conflicting evidence about the risks faced by people who regularly work with radiation.This includes nuclear power workers and medical professionals who use radioactive technology, such as X-r
