Hello and welcome to healthcare forum.
After proper treatment of pulmonary tuberculosis
, in the lung appears healed lesions of it , which are prone to calcify as natural body process and forms such density visible on x ray
you should not worry regarding this x ray reporting as you dont have any chest symptoms and you are not sick.
So as the disease is inactive most probably you will not have any problem in employment.
I hope i have answered your query.
Best wishes for your health.
