Week 9: Radiofrequency Fields Flashcards
1
Q
Electromagnetic radiation
A
Energy containing, massless photon particles that travel in transverse waves at the speed of light
Amplitude and frequency can be altered to transmit different signals
2
Q
Radiofrequency fields
A
Efficient and useful mode of transmitting and receiving information
Small component of the electromagnetic spectrum
Non-ionizing
Microwaves, heat lamps, rock music, MRI
3
Q
Are RF associated with health effects?
A
No clear causal association
Perhaps excessive phone use and glioma - RR of 1.4
4
Q
RF output power variations
A
Varies through different time periods due to frequency of calls and density of wireless networks
