PREPARATION Samples for measuring the activity of beta-gamma emitting radionuclides in counting samples spectrometric method

摘要

1. A method for preparing samples for measuring the activity of beta-gamma-emitting radionuclides in the counting samples spectrometric method comprising screening a sample product and the subsequent concentration of the sample by heating, characterized in that the heating is carried out by the action of microwave radiation with a power of 0,8-6,0 kW .2. A method according to claim 1, characterized in that the sampling performed by nesypuchego product as its whole kuska.3. A method according to claim 2, characterized in that the piece izmelchayut.4. A method according to claim 3, characterized in that prior to grinding, drying the piece and the piece of the dried particulate mixed with vodoy.5. A method according to claim 1, characterized in that the sampling is carried out by bulk produkta.6. A method according to claim 5, characterized in that the sample is mixed with the loose product vodoy.7. A method according to claim 5, characterized in that the bulk product sample when exposed to microwave radiation arranged in a crucible made of opaque to exposure to microwave radiation materiala.8. A method according to claim 1, characterized in that the sample products when exposed to microwave radiation arranged in a crucible made of transparent to microwave radiation exposure to the material.
