align="center"><img src="https://img78.chem17.com/2/20210325/637523088165161535433.jpg" width="400" height="400" align="middle" alt="" /></p><p> </p><br /> 放射性同位素，也叫不穩(wěn)定核素，是相對于穩(wěn)定核素來說的。它是指不穩(wěn)定的原子核，能自發(fā)地放出射線（如α射線、β射線等），通過衰變形成穩(wěn)定的核素，衰變時(shí)放出的能量稱為衰變能。<br /><span style="font-size: 14px;"> 原子核發(fā)生α衰變或β衰變時(shí)所形成的子核往往處于激發(fā)態(tài)能級。激發(fā)態(tài)是不穩(wěn)定的，通過放射γ射線（也叫γ光子）退激或級聯(lián)退激到基態(tài)，原子核由高能態(tài)自發(fā)地向低能態(tài)躍遷，叫做γ躍遷，也叫γ衰變。</span><br /><span style="font-size: 14px;"> 1.活度計(jì)原理</span><br /><span style="font-size: 14px;"> 活度計(jì)采用高壓密封井型電離室作為探測器，利用精密微電流測量系統(tǒng)進(jìn)行電離電流的測量。</span><br /><span style="font-size: 14px;"> 2.活度計(jì)的使用</span><br /><span style="font-size: 14px;"> 活度計(jì)可以較大量程的檢測80多種標(biāo)定過的核素，檢測范圍0.1 μCi-6 Ci左右，小于10 μCi時(shí)檢測結(jié)果僅供參考，檢測單位可以在Ci和Bq之間切換。儀器自帶衰減校正功能，可以計(jì)算出檢測樣品在任意時(shí)間的放射性活度。使用方法較為簡單，先選定核素種類，將活度計(jì)清零（本底校正），然后將待測樣品放入活度計(jì)，待活度計(jì)顯示器的示值穩(wěn)定3秒后，再進(jìn)行讀數(shù)即可。</span></span> </div>
