The X-rays ionise the air around the gold leaf electroscope.
Charges in the air of the opposite sign to that on the electroscope are attracted to the electroscope and discharge it.
If X-rays are incident on gold leaf electroscope , leaves always collapse whatever be the charge on leaves.

Positively Charged Gold Leaf Electroscope in Evacuated Condition
When a positively charged gold leaf electroscope is placed in an evacuated condition and exposed to X-rays, several interesting phenomena occur due to the interaction between the X-rays and the charged particles in the electroscope.
Effect of X-rays on Positively Charged Electroscope
- The X-rays will ionize the air molecules within the electroscope, creating positively and negatively charged ions.
- The positively charged ions will be attracted to the negatively charged gold leaves, causing them to diverge even further.
- This divergence of the gold leaves indicates an increase in the positive charge on the electroscope due to the ionization by X-rays.
- The overall effect is that the positively charged electroscope becomes even more positively charged in the presence of X-rays.
Explanation of Phenomena
- The X-rays have enough energy to ionize the air molecules, generating free electrons and positively charged ions.
- The positively charged ions are attracted to the negatively charged gold leaves, neutralizing some of the negative charge and causing the leaves to diverge more.
- This process continues as long as the X-rays are present, leading to a further increase in divergence of the gold leaves.
- The positively charged electroscope acts as a detector for the ionizing radiation, showcasing the ionization process caused by X-rays.
In conclusion, when a positively charged gold leaf electroscope is placed in an evacuated condition and exposed to X-rays, the X-rays ionize the air molecules, leading to an increase in positive charge on the electroscope and causing the gold leaves to diverge even further. This phenomenon demonstrates the interaction between charged particles and ionizing radiation in a controlled environment.
