WebAlthough we cannot see or feel the presence of radiation, it can be detected and measured in the most minute quantities with quite simple radiation measuring instruments. Radiation Dose Sunlight feels warm because our body absorbs the infra-red rays it contains. But, infra-red rays do not produce ionization in body tissue.
WebMeasure the background radiation for 60 seconds: write down the reading. Since background radiation varies with time, it may be desirable to make several counts and average the results. Record the reading. Readings may vary, but a range of 20-100 counts/min, or a reading of approximately 0.02 mR/hr (i.e. 0.2 on the 0.1 range setting), or … csm from simplilearnBackground radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources. Background radiation originates from a variety of sources, both natural and artificial. These include both cosmic radiation and … See more Background radiation is defined by the International Atomic Energy Agency as "Dose or dose rate (or an observed measure related to the dose or dose rate) attributable to all sources other than the one(s) specified. So … See more Atmospheric nuclear testing Frequent above-ground nuclear explosions between the 1940s and 1960s scattered a substantial amount of radioactive contamination. … See more In a radiation metrology laboratory, background radiation refers to the measured value from any incidental sources that affect an instrument when a specific radiation source sample is being measured.
