This work has been carried out to monitor and decrease the natural radiation exposure at the Hantepe beach (anakkale, Turkey). A 0.25- to 0.30-m-thick layer of sand was scraped, removed and deposited in a safe place in order to decrease peoples exposure to radiation and to relieve relevant radiophobia. The original mean value of dose rate on the beach was 1.38 Gy h(1) at the contact and 1.0 Gy h(1) at 1 m above the ground. After the scraping process, the mean value of dose rate decreased to 0.98 Gy h(1) at the contact and to 0.78 Gy h(1) at 1 m above the ground. One year later, these values decreased to 0.70 Gy h(1) at the contact and to 0.56 Gy h(1) at 1 m above the ground. The effective original dose rate of 1.2 mSv y(1) decreased to 0.95 mSv y(1) after the surface treatment and to 0.69 mSv y(1) one year later.
