Radionuclides are found in different media including, soils, air, water, plants, vegetables, and in fruits etc. These radionuclides and their isotopes contaminate the environmentand could cause deleterious effect on human beings when ingested or inhaled. The cocoa plantation is a new plantation developed two years ago in the State for resource management and enhanced cocoa production. In situ measurement of the background ionising radiation was conducted with Radex (1212) radiation survey meterwhich measured background ionising radiation level in micro Seviert per hour. The measured values were converted to annual equivalent dose rate and annual effective dose. The mean background ionizing radiation (BIR) measured was obtained as 0.083µSv/hr and a mean annual BIR of 0.727mSv/yr. The obtained mean annual BIR obtained is lower than the worldwide BIRof 2.4 mSv/yr. The annual equivalent dose rate of radiation obtained in the plantation was ranged between 0.1261 to 0.2067mSv/yr with a mean value of 0.1454 mSv/yr. The mean annual effective dose was 0.1015 mSv/yr and lower than the recommended 1 mSv/yr as a safety limit for the public. Therefore regulatory controls are not necessary for now as this is a new plantation.
