One of the key principles of radiological protection is to keep doses As Low As Reasonably Practicable (ALARP). This is achieved by various combinations and variations of three basic Parameters: Time of exposure, Distance from the source of radiation, Shielding to reduce the radiation. 

These parameters also apply to protection from COVID-19.

Time
In spaces that are enclosed or without adequate ventilation, spend as little time as possible on the tasks you need to do.

Distance
Maintain a distance of at least 2m between people.

Shielding
Always wear a mask where possible to avoid the spreading of the virus.  Masks can help to prevent the spreading of saliva droplets from speaking, coughing and sneezing.
