1. A method for sterilizing an organic product in a chamber having a controlled atmosphere, wherein one or more samples of the organic product is placed in the chamber, the method comprising:
introducing a specified quantity of a gaseous composition comprising a predefined proportion of ozone into the chamber;
subjecting the one or more samples to the gaseous composition and ultraviolet radiation using at least one ultraviolet tube light, for a predefined time period to sterilize the one or more samples, wherein the one or more samples is accommodated on one or more perforated shelves provided inside the chamber, wherein the at least one ultraviolet tube light is arranged in a manner to radiate an entire surface area of each sample of the organic product accommodated on each perforated shelf, wherein the specified quantity of the gaseous composition further comprises a predefined proportion of carbon monoxide, wherein the carbon monoxide to carbonize the one or more samples of the organic product, and wherein the organic product comprises blood as a constituent; and determining by the controller the specified quantity of the gaseous composition, the predefined proportion of ozone, the predefined proportion of carbon monoxide, and the predefined time period using a model stored in a memory of the controller, wherein a quantity of samples of the organic product, and a type of the organic product provided as an input to the model, wherein the quantity of samples and the type of the organic product is received by the controller via an input interface, and wherein the model comprises operating information of the chamber required for sterilization of a plurality of types and quantities of organic products;
maintaining:
a humidity level of the atmosphere in the chamber in a range of 90 to 100% by using a humidifier unit and a controller, and
a temperature within the chamber in a range of −10 to 5 degree Celsius by a plurality of condensers surrounding the chamber;
releasing the gaseous composition out of the chamber upon completion of the predefined time period, while introducing at least one of oxygen and atmospheric air into the chamber, until presence of the gaseous composition in the atmosphere of the chamber reaches below a threshold value, wherein the presence of the gaseous composition is monitored by the controller; and
procuring the one or more samples through an exit of the chamber in an insulated arrangement, wherein the exit is opened when the gaseous composition is released from the chamber up to the threshold value.
