ได้ทำการตรวจวัดและวิเคราะห์ปริมาณกัมมันตภาพจำเพาะของนิวไคลด์กัมมันตรังสีธรรมชาติ (40K, 226Ra และ 232Th) และที่มนุษย์สร้างขึ้น (137Cs) ที่มีอยู่ในตัวอย่างข้าวสารเหนียวที่จัดซื้อมาจากร้านค้าและห้างสรรพสินค้าในจังหวัดสงขลา รวมทั้งสิ้น 30 ตัวอย่าง โดยใช้หัววัดรังสีแบบเจอร์มาเนียมบริสุทธิ์สูง (HPGe) และระบบวิเคราะห์แบบแกมมาสเปกโตรเมตรี ณ ห้องปฏิบัติการทางรังสี สถาบันเทคโนโลยีนิวเคลียร์แห่งชาติ (องค์การมหาชน) (สทน.) จากผลการวิเคราะห์ปริมาณกัมมันตภาพจำเพาะของ 40K, 226Ra, 232Th และ 137Cs ในตัวอย่างข้าวสารเหนียว พบว่า มีค่าพิสัยอยู่ในช่วง < 592.21 – 896.36 < 3.73 - 11.92 < 2.49 - 7.84 และ <1.54 - < 2.35 Bq/kg ตามลำดับ มีค่าเฉลี่ยเป็น 800.71 ± 37.93 7.25 ± 2.23 4.32 ± 1.54 และ<1.92 Bq/kg ตามลำดับ และยังได้ทำการประเมินค่าดัชนีความเสี่ยงทางรังสีที่เกี่ยวข้องและค่าความเสี่ยงต่อการเป็นมะเร็ง ตลอดชีพจากการบริโภคข้าวสารเหนียว พบว่า ค่าที่ตรวจวัดได้ยังอยู่ในเกณฑ์ที่ปลอดภัย นอกจากนี้ยังได้เปรียบเทียบค่าที่ตรวจวัดได้นี้กับข้อมูลวิจัยของสำนักงานปรมาณูเพื่อสันติ ข้อมูลวิจัยในประเทศไทยและต่างประเทศ รวมทั้งค่าที่แนะนำกันทั่วไปอีกด้วย
