Notes:
The International Radon Project (IRP) is a research initiative that was launched in the 1980s by the World Health Organization (WHO) in order to study the health effects of radon exposure and to develop guidelines for the protection of human health from radon-induced radiation. Radon is a naturally occurring radioactive gas that is produced by the decay of uranium and radium, which are found in small amounts in soil, rock, and water. When radon is released into the air, it can be inhaled into the lungs, where it can expose the body to ionizing radiation and increase the risk of lung cancer.

Notes:
Black soil is known for its ability to hold moisture. This soil can retain moisture for a long time, which can help crops during dry seasons. Black soil is sticky when wet, so it’s difficult to work with. It’s usually tilled after the first shower or during the pre-monsoon period.
The ability of soil to retain water is related to the size of its particles. Clay soil has small, fine particles, so it retains the most water. Sand has larger particles and retains the least water. Silt and loam have medium-size particles and retain a moderate amount of water.
