Molecular Biology Problem Solver 16. Sách được nhiều nhà khoa học có uy tín, nhiều kinh nghiệm trong nghiên cứu thực nghiệm trình bày những vấn đề thường hay phát sinh trong phòng thí nghiệm. Do vậy mà sách không trình bày các protocol hay quy trình như các sách khác, thay vào đó các tác giả sẽ trình bày các vấn đề nhằm giúp giúp đọc giả: Tự nâng cao khả năng chẩn đoán nguyên nhân khi gặp các vấn để về kỹ thuật, quy trình, hóa chất, thuốc thử trong quá trình thực nghiệm trong phòng thí. | Your Count-Rate Meter Detects Radiation on the Outside of a Box Containing I mCi of a 32P Labeled dATP Is It Contaminated .

I66 The information within this chapter is designed as a supplement not a replacement to the training provided by your institutional rules and or radiation safety officer. At the very least there are some 10 fundamental rules to consider when working with radioactivity Amerhsam International 1974 1. Understand the nature of the hazard and get practical training. 2. Plan ahead to minimize time spent handling radioactivity. I42 Volny Jr. 3. Distance yourself appropriately from sources of radiation. 4. Use appropriate shielding for the radiation. 5. Contain radioactive materials in defined work areas. 6. Wear appropriate protective clothing and dosimeters. 7. Monitor the work area frequently for contamination .
