Due to the presence of monazite sand, there have been prior instances of radioactive contamination in the Pasir Ris region, including White Sands beach. Thorium, a radioactive element, is found in trace quantities in the naturally occurring mineral monazite. There is no evidence to support a persistent danger to the public's health, and the level of radioactive contamination in the region has been found to be within safe limits.
The Pasir Ris area's radioactive contamination was thoroughly evaluated by the Singaporean government in 2014, and it was determined that there was little danger to the general public's health. To guarantee that the area is still secure for use by the public, the government has put in place a monitoring and control program.
While there is nothing to worry about, it is always a good idea to exercise proper caution when going to the beach or any other outdoor location in Singapore. Examples of these precautions include wearing sunscreen, drinking plenty of water, and adhering to any written safety instructions.
