A chest x ray uses 14 keVkeV photons. A 77 kgkg person receives a 26 mremmrem dose from one x ray that exposes 25%% of the patient's body. How many x ray photons are absorbed in the patient's body? **Educational Context:**In the scenario presented, a chest X-ray utilizes photons with an energy of 14 keV (kilo-electronvolts). The subject is a 77 kg individual who receives a radiation dose of 26 mrem (millirem) from a single X-ray procedure that exposes 25% of their body to the radiation.**Question:***Part A:* How many X-ray photons are absorbed in the patient's body?**Solution Input:**The attempted calculation for the number of absorbed photons is represented as:\[ N = 2.63 \times 10^{12} \]**Feedback:**Upon submission, the response was marked incorrect, with a note indicating one more attempt is allowed to solve the problem correctly. The question challenges the reader to apply concepts of physics related to dosimetry, energy absorption, and the interaction of photons with matter to determine the number of photons absorbed during the X-ray.

Question

A chest x ray uses 14 keVkeV photons. A 77 kgkg person receives a 26 mremmrem dose from one x ray that exposes 25%% of the patient's body. How many x ray photons are absorbed in the patient's body?

**Educational Context:**

In the scenario presented, a chest X-ray utilizes photons with an energy of 14 keV (kilo-electronvolts). The subject is a 77 kg individual who receives a radiation dose of 26 mrem (millirem) from a single X-ray procedure that exposes 25% of their body to the radiation.

**Question:**

*Part A:* How many X-ray photons are absorbed in the patient's body?

**Solution Input:**

The attempted calculation for the number of absorbed photons is represented as:

\[ N = 2.63 \times 10^{12} \]

**Feedback:**

Upon submission, the response was marked incorrect, with a note indicating one more attempt is allowed to solve the problem correctly.

The question challenges the reader to apply concepts of physics related to dosimetry, energy absorption, and the interaction of photons with matter to determine the number of photons absorbed during the X-ray.
