+### getTotalRadiation(timeStamp)
+
+Retrieves the total radiation (QuantityType<Intensity>) of the sun at the requested instant.
+Thing method only applies to Sun thing type.
+
+```java
+ val totalRadiation = sunActions.getTotalRadiation(ZonedDateTime.now)
+ logInfo("AstroActions", "Currently, the total sun radiation is {}", totalRadiation.toString)
+```
+
 ## Tips
 
 Do not worry if for example the "astro dawn" is undefined at your location.
