Flashcards in RF Radiation Safety Deck (10):
1

The reproductive effects of video display terminals have been attributed to ionizing radiation and:

Low frequency pulsed magnetic fields

2

At higher frequencies (95 GHz) the tissues most strongly impacted is

The skin. At 95GHz the majority of the energy is absorbed in the surface of the skin

3

OSHA standard for far field exposure to microwave radiation averaged over any 0.1 hour period

10 mW/cm^2

4

Radio-frequency exposure limits are based on

heating beyond the ability of the body to cool.

5

Tissues most likely impacted by 30-300 MHz radio frequencies

Eyes and Testes. Not easily cooled.

6

Resonant frequency for reference man

70 MHz. Exhibits a wavelength on the order of magnitude of the effective diameter of reference man.

7

Radio-frequency radiation can induce currents in the human body at low frequencies and can be a hazard above exposure limits. These typically manifest as

Heating of the ankles

8

The TLV for exposure to radiation from a microwave oven is:

10 mW/cm^2

9

To limit possible exposure to radiation from television receivers, the NCRP recommends that children sit no closer than:

6 feet. The FDA limits the exposure rate at the surface of television sets today at 0.1 mR/hr

10

The FDA standard for microwave oven leakage at 5cm or more from the external surface of the oven, prior to sale is:

1 mW/cm^2. The limit goes to 10 mW/cm^2 once in operation (TLV for microwaves)
