What is the LD 50 30 For humans?

The dose of radiation expected to cause death to 50 percent of an exposed population within 30 days (LD 50/30). Typically, the LD 50/30 is in the range from 400 to 450 rem (4 to 5 sieverts) received over a very short period.

Thereof, what does LD 50 30 and SED 50 refer to?

For this reason, LD50 figures are often qualified with the mode of administration, e.g., "LD50 i.v." The related quantities LD50/30 or LD50/60 are used to refer to a dose that without treatment will be lethal to 50% of the population within (respectively) 30 or 60 days.

Subsequently, question is, how many REM is fatal? Effects of Radiation Levels on the Human Body

Dose-rem Effects
200-300 Serious radiation sickness effects as in 100-200 rem and hemorrhage; exposure is a Lethal Dose to 10-35% of the population after 30 days (LD 10-35/30).
300-400 Serious radiation sickness; also marrow and intestine destruction; LD 50-70/30.

In this manner, what is ld50 used for?

The median lethal dose (or LD50) is defined as the dose of a test substance that is lethal for 50% of the animals in a dose group. LD50 values have been used to compare relative acute hazards of industrial chemicals, especially when no other toxicology data are available for the chemicals.

How much radiation is in a banana?

The radiation exposure from consuming a banana is approximately 1% of the average daily exposure to radiation, which is 100 banana equivalent doses (BED). The maximum permitted radiation leakage for a nuclear power plant is equivalent to 2,500 BED (250 μSv) per year, while a chest CT scan delivers 70,000 BED (7 mSv).
