  • 照射線量 - 放射線による乾燥空気の電離量。


  • 吸収線量 - 放射線の照射によって単位質量あたりの物質が吸収するエネルギー量。



防護量


放射線防護に用いられる生物学的効果を考慮した量。




  • 等価線量 - 人体の各臓器の放射線被曝による確率論的影響のリスクの程度を表す量。臓器吸収線量に放射線加重係数を乗じたもの。


  • 実効線量 - 個人の放射線被曝による確率論的影響のリスクの程度を表す量。等価線量にその臓器の組織加重係数を掛けた値の総和。

It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
